If $$'I'$$ is the intensity of absorbed light and $$'C'$$ is the concentration of $$AB$$ for the photochemical process, $$AB +$$ $$hv \to A{B^ * },$$ the rate of formation of $$A{B^ * }$$ is directly proportional to
A.
$$C$$
B.
$$I$$
C.
$${I^2}$$
D.
$$C.I$$
Answer :
$$I$$
Solution :
NOTE: The rate of photochemical process varies with the intensity of absorption.
Since greater the intensity of absorbed light more photons will fall at a point, and further each photon causes one molecule to undergo reaction.
