Question

What is the difference between photolysis and photochemical reaction

Answer 1

HEY MATE....

HERE'S UR ANSWER...

THERMOCHEMICAL REACTIONS

1. These reactions involve absorption or evolution of heat.
2. They can take place even in absence of light i.e. dark.
3. Temperature has significant effect on the rate of a thermochemical reaction. Temperature has very little effect on the rate of a photochemical reaction.
4. The free energy change ∆G of a thermochemical reaction is always negative.
5. They are accelerated by the presence of a catalyst.

Photochemical reaction

1. These reactions involve absorption of light.
2. The presence of light is the primary requisite for the reaction to take place
3. Temperature has very little effect on the rate of a photochemical reaction. Instead, the intensity of light has a marked effect on the rate of a photochemical reaction.
4. The free energy change ∆G of a photochemical reaction may not be negative.
5. Some of these are initiated by the presence of a photosensitizer. However a photosensitizer acts in a different way than a catalyst.
