Question
If I is the intensity of absorbed light and C is the concentration of AB for photochemical process. AB + hv → AB*, the rate of formation of AB* is directly proportional to :
Options
A.C
B.I
C.I2
D.C.I2
Solution
In photochemical reactions, the rate of reaction depends upon first step in which attacking reagent homolyse to give free radicals. The rate of photo- dissociation depends upon the intensity (I) of the light, thus, rate ∞ intensity of light absorbed.
