Question

Explain photochemical reaction.

Answer 1

• Photochemical reactions are the type of reactions that requires light energy to occur.
• A very good example of a photochemical reaction is the reaction occurring during photosynthesis.
• During photosynthesis water is hydrolyzed into oxygen and hydrogen in the presence of diffused sunlight.

The equation of reaction is-

$2{\mathrm{H}}_2\mathrm{O}\stackrel{\mathrm{diffused}\mathrm{sunlight}}{\to }2{\mathrm{H}}_2+{\mathrm{O}}_2$
