Energy transfer in reactions Flashcards
1
Q
What are exothermic and endothermic reactions
A
An exothermic reaction is one which gives out energy to the surroundings, usually in the form of heat which is shown by a rise in temperature . Endothermic reaction is one which takes in energy from the surrounding area using the form of heat which is shown by falling temperature
2
Q
What happens during a chemical reaction
A
Julie can call reaction old bonds are broken and new ones are formed
3
Q
What happens in exothermic reaction
A
Exothermic reaction the energy released in bond formation is greater than the energy used in breaking your bonds
4
Q
What happens in endothermic reaction
A
Endothermic reaction the energy required to break the bonds is greater than the energy released when Bonds are formed
