In a photochemical reaction,the ratio of the number of dissociated molecules to the number of quanta of absorbed energy is called:

Which of the following is true for a photochemical reaction?

If $I$ is the intensity of absorbed light and $C$ is the concentration of $AB$ for the photochemical process $AB + h\nu \to AB^*$,the rate of formation of $AB^*$ is directly proportional to

The law of photochemical equivalence was given by

Silver nitrate is usually kept in coloured bottles because it is

According to the law of photochemical equivalence,the energy absorbed (in $ergs \ mol^{-1}$) is given as ($h = 6.62 \times 10^{-27} \ erg \ s$,$c = 3 \times 10^{10} \ cm \ s^{-1}$,$N_A = 6.02 \times 10^{23} \ mol^{-1}$):
