Solution
The correct option is B False
The chemical reactions in which the light energy is liberated or absorbed is called photochemical reactions. Example, photosynthesis. It is a process by which green plants make their own food from carbon dioxide and water in the presence of sunlight and chlorophyll is called photosynthesis. During this process, oxygen gas is released.
In thermochemical reactions, the energy is either released or absorbed during the chemical reaction. Chemical reactions which liberate heat are called exothermic reactions and those which absorb heat are called endothermic reactions.
