13. Chemical Energetics Flashcards
1
Q
What is the process of exothermic?
A
- Reactions give out thermal energy to surroundings
- Temperature of reaction mixture will increase
- container will feel warm
2
Q
What is the process of endothermic?
A
- Reactions absorb thermal energy from surrounding
- Temperature of the reaction mixture will decrease
- container will feel cool
3
Q
Does the curve goes up or down for exothermic reaction?
A
goes up
4
