The main differences between exothermic reactions and endothermic reactions are:
Exothermic reactions are reactions that give off energy (light, electrical or mainly heat), causing the surroundings to warm up. Endothermic reactions are reactions that absorb energy, causing the surroundings to cool down.
The products of an exothermic reaction have less energy, or less total enthalpy, than of it's reactants. This is due to the reactants containing more stored energy because energy from external sources is not required. This also gives the products more stability because in order to achieve a reversible reaction and break the chemical bonds of the products, you will need to apply more energy to it.
The opposite is for endothermic reactions. The products of the reaction have a greater total enthalpy of the reactants, causing the reactants stored energy to decrease. This produces less stable products that need less energy to break their bonds in a reversible reaction.
Finally most exothermic reactions are spontaneous, where as most endothermic reactions are not spontaneous as they generally need energy applied to them before they start.
Endothermic reactions absorb heat from their surroundings, causing a decrease in temperature, while exothermic reactions release heat into their surroundings, causing an increase in temperature. An example of an endothermic reaction is the reaction between ammonium nitrate and water, while an example of an exothermic reaction is the combustion of gasoline.
Examples for exothermic reaction:
- fermentation is a example of exothermic reaction
- combustion reaction of fuels
- adding concentrated acid to water
- most polymerisation reaction
- burning of substance
- photosynthesis
- a chemical cold pack consisting primarily of ammonium nitrate and water
- evaporation of water
- preparation of ozone by passing silent electric discharged through oxygen
Endothermic reactions are chemical reactions that use heat as part of the reactant. Heat is absorbed into the reaction in order for it to continue.
Exothermic reactions are chemical reactions that release heat as a product of the reaction.

Do all acid reactions give off heat?
Not all acid reactions give off heat. Some acid reactions are endothermic, meaning they absorb heat from the surroundings instead of releasing it. Examples of endothermic acid reactions include the reaction of citric acid with water.
Examples of endothermic and exothermic reactions?
An example of an endothermic reaction is the reaction between ammonium nitrate and water, which absorbs heat from the surroundings, causing the mixture to feel cold to the touch. An example of an exothermic reaction is the combustion of methane gas with oxygen, which releases heat into the surroundings, causing the surroundings to feel warmer.
What is the type of chemical reaction in which heat energy is absorbed?
An endothermic reaction is a type of chemical reaction in which heat energy is absorbed from the surroundings. This results in a decrease in temperature of the surroundings and an increase in the energy of the reactants.
What is the difference between endothermic and exothermic And give examples?
Chemical reactions that release energy in the form of heat, light, or sound are called exothermic reactions. Example: Mixture of sodium and chlorine to yield table salt In other words, combination reactions are exothermic. Reactions that absorb energy or require energy in order to proceed are called endothermic reactions. For example: In the process of photosynthesis, plants use the energy from the sun to convert carbon dioxide and water to glucose and oxygen.
What is a exotermic reaction?
An exothermic reaction is a chemical reaction that releases energy to its surroundings in the form of heat. This type of reaction typically results in a temperature increase in the surrounding environment. Examples of exothermic reactions include combustion and many neutralization reactions.
What is the difference between Endothermic and Exothermic in five to ten points?
Endothermic reactions absorb heat from the surroundings, causing a decrease in temperature, while exothermic reactions release heat into the surroundings, causing a temperature increase. Endothermic reactions require an external heat source to proceed, while exothermic reactions release enough heat to sustain themselves. Endothermic reactions have a positive change in enthalpy (βH), indicating absorption of energy, while exothermic reactions have a negative βH, indicating energy release. Endothermic reactions are typically non-spontaneous at low temperatures, requiring energy input to occur, while exothermic reactions are often spontaneous as they release energy. Examples of endothermic reactions include photosynthesis and ice melting, while examples of exothermic reactions include combustion and neutralization reactions.
What chemical reactions are exothermic?
Some examples of exothermic reactions include combustion reactions (such as burning wood or gasoline), neutralization reactions between an acid and a base, and some types of oxidation reactions. These reactions release heat and energy to their surroundings.

What are some examples of endothermic reactions that are endothermic as well?
All ENDOthermic reactions are of course ENDOthermic by themselves, aren't they?
Do all acid reactions give off heat?
Not all acid reactions give off heat. Some acid reactions are endothermic, meaning they absorb heat from the surroundings instead of releasing it. Examples of endothermic acid reactions include the reaction of citric acid with water.
What are some examples of endothermic equations and exothermic equations?
An example of an endothermic reaction is the reaction between barium hydroxide and ammonium thiocyanate, which absorbs heat from the surroundings. An example of an exothermic reaction is the combustion of methane, which releases heat into the surroundings.
Which chemical reaction is responsible for producing heat?
Exothermic reactions are responsible for producing heat as they release energy in the form of heat during the reaction. This occurs when the energy released in making new bonds is greater than the energy required to break the existing bonds. Examples include combustion reactions, some oxidation reactions, and neutralization reactions.
Examples of endothermic and exothermic reactions?
An example of an endothermic reaction is the reaction between ammonium nitrate and water, which absorbs heat from the surroundings, causing the mixture to feel cold to the touch. An example of an exothermic reaction is the combustion of methane gas with oxygen, which releases heat into the surroundings, causing the surroundings to feel warmer.
What is exothermil?
It seems like you're referring to the term "exothermic." Exothermic reactions release heat to their surroundings, resulting in an increase in temperature. This energy release is usually in the form of heat, but it can also manifest as light. Examples of exothermic reactions include combustion and neutralization reactions.
What is the type of chemical reaction in which heat energy is absorbed?
An endothermic reaction is a type of chemical reaction in which heat energy is absorbed from the surroundings. This results in a decrease in temperature of the surroundings and an increase in the energy of the reactants.
What is a chemical reaction that doesn't releases energy?
A chemical reaction that doesn't release energy is an endothermic reaction. There are few reactions that are endothermic compared to exothermic reactions (reactions that release energy as heat). Endothermic reactions actually take in heat from the environment and that is why you see a temperature drop. Examples of endothermic reactions: Electrolysis A reaction between ethanoic acid and sodium carbonate A thermal decomposition reaction (as you put heat into the reaction to break something down) Hope this helped.
