Heat generally speeds up the reaction, while cold will slow it down. The enzymes in the cold are frozen.

Do catalysts affect temperature?
A catalyst affects the speed of a chemical reaction. If the chemical reaction gives off heat, the reaction may affect the temperature, but the catalyst by itself doesn't affect the temperature.
What material burns cold?
There is no material that burns cold. Burning is a chemical reaction that releases heat energy.
What is a heat reaction?
This the heat released during a chemical 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.
Heat of reaction for a chemical reaction symbol?
The symbol used to represent the heat of reaction in a chemical equation is ΔH. It indicates the enthalpy change of the reaction, which is the heat exchanged during a chemical reaction at constant pressure.
Do catalysts affect temperature?
A catalyst affects the speed of a chemical reaction. If the chemical reaction gives off heat, the reaction may affect the temperature, but the catalyst by itself doesn't affect the temperature.
When you activate an instant cold pack and water mixes with a chemical and the pack gets very cold what example is this?
This is an example of an endothermic chemical reaction, where energy is absorbed from the surroundings in the form of heat, causing the pack to become cold. The reaction between the chemicals in the instant cold pack and water absorbs heat from the environment, resulting in the cooling effect.
Is an icy hot a chemical reaction or a physical reaction?
Icy Hot is a physical reaction. When applied to the skin, it produces a sensation of heat or cold by irritating nerve endings, rather than undergoing a chemical reaction.
When you activate an instant cold pack water mixes with a chemical and the pack gets very cold This is an example of?
an endothermic reaction where the chemical reaction absorbs heat from its surroundings, causing the pack to cool down.
Why does a cold pack get cold when the chemical reacts?
Cold packs use an endothermic reaction, meaning it absorbs heat from its surroundings, resulting in a decrease in temperature. The reaction between the chemicals inside the cold pack and water activates this process, causing the pack to feel cold.
What material burns cold?
There is no material that burns cold. Burning is a chemical reaction that releases heat energy.
What is a chemical reaction that absorbs heat?
An example of a chemical reaction that absorbs heat is the reaction between baking soda (sodium bicarbonate) and vinegar (acetic acid) to produce carbon dioxide gas. This reaction is endothermic, meaning it absorbs heat from its surroundings, causing the mixture to feel cold to the touch.
What is a chemical reaction that's absorbs energy called?
An Endothermic reaction. If you touch the reaction vessel it will feel cool/cold, as it is taking in heat energy. By contract an Exothermic reaction is one that gives out heat. If you touch the reaction vessel it will feel warm/hot as it is liberating heat energy.
What is a endopthermic reaction?
An endothermic reaction is a chemical reaction that absorbs heat from its surroundings, resulting in a decrease in temperature. This type of reaction requires energy input to proceed and is often associated with feeling cold. Examples include the melting of ice and the evaporation of water.
Does adding heat energy affect the rate of reaction in a chemical change?
it depends on what chemicals used
What is a heat reaction?
This the heat released during a chemical reaction.
Is endothermic a chemical reaction?
Yes. A chemical reaction which absorbs heat during the reaction. The opposite to exothermic which releases heat during the reaction.
