please let me know the use of photochemical reactions in GREEN CHEMISTRY?

Answer 1

This is a confusing question. There is luminescence which
produces a slightly green light, this is due to the excitation of
atoms and the degradation of electron energy as it changes from a higher to a lower energy state. (Some energy is lost and it manifests itself in a greenish light).

The other answer could be photosynthesis. This is the use of light energy to allow plants to grow. You could this green chemistry because the plant leaves are green...

Hope this helps.

Answer 2

Chlorophyll, which is green in color, is the catalyst in the photochemical reaction in green plants. This process, called photosynthesis, uses the energy of the sun to converts carbon dioxide in the air and other chemicals into material in the plants.

Part of this process is the emission of oxygen by the plants.

Without carbon dioxide, all the green plants would die. Without the oxygen and the food from plants, all the animals would die.

Answer 3

it's used to conserve solvent. it also is the only way certain reactions happen at all
