What is the enthalpy of a reaction?
The amount of energy that is used or released as heat in a reaction.
What is the use of heat as a convenient measurement of chemical energy in any reaction?
Energy is measured in joules. Sometimes the older unit "calorie" is used instead - this is a unit defined on the basis of heat, but it is still a unit of energy.
What is a heat reaction?
This the heat released during a chemical reaction.
Energy is lost from a reaction in a form of what?
Energy is lost from a reaction in the form of heat. This heat is often referred to as exothermic heat, as it is released from the system during the reaction.
A chemical reaction that gives off heat is most likely to be what?
An exothermic reaction is a chemical reaction that gives off heat. In an exothermic reaction, energy is released in the form of heat to the surroundings.

What is the difference between heat of reaction and molar heat of reaction?
The heat of reaction is the total amount of heat released or absorbed during a chemical reaction, while the molar heat of reaction is the heat of reaction per mole of a substance involved in the reaction. The molar heat of reaction allows for comparison of the energy changes between different reactions on a per mole basis.
What is heat of the reaction is releasesd?
If heat from a reaction is released, it is an exothermic reaction.
What is a heat reaction?
This the heat released during a chemical reaction.
Energy is lost from a reaction in a form of what?
Energy is lost from a reaction in the form of heat. This heat is often referred to as exothermic heat, as it is released from the system during the reaction.
How are endothermic reaction different from exothermic reaction?
Exothermic reaction: with release of heat Endothermic reaction: with absorption of heat
How does temperature affects reaction rate?
if the reaction is exothermic (creates heat) then adding heat will cause the reaction to run in the reverse direction if the reaction is endothermic (requires heat) then heat will speed it up
What happens in an endothermic reaction?
An endothermic reaction need heat to occur.
A chemical reaction that gives off heat is most likely to be what?
An exothermic reaction is a chemical reaction that gives off heat. In an exothermic reaction, energy is released in the form of heat to the surroundings.
A reaction that absorbs energy is called?
Endothermic reaction. An endothermic reaction absorbs energy from its surroundings in the form of heat, causing a decrease in temperature.
Does anybody know the formula for endothermic reaction and exothermic reaction?
An endothermic reaction absorbs heat from its surroundings, while an exothermic reaction releases heat to its surroundings. The general formula for an endothermic reaction is: reactants + heat → products, and for an exothermic reaction: reactants → products + heat.
