Q
Give examples of endothermic reactions and how they are used in everyday life
A
Photosynthesis uses light energy
Used in everyday life by sport injury packs and thermal decomposition

Q
What happens if a reversible reaction is exothermic in one direction?
A
If it’s exothermic In one direction, it’s endothermic in the opposite direction. The same amount of energy is transferred
