Silver nitrate is usually kept in coloured bottles because it is

For a photochemical reaction,if the intensity of absorbed light is $I$ and the concentration of $AB$ is $C$. Given the reaction $AB + h\nu \rightarrow AB^*$,the rate of formation of $AB^*$ is proportional to:

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

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

For the reaction taking place in the presence of sunlight,the order of reaction is
$H_2 + Cl_2 \xrightarrow{\text{Sunlight}} 2HCl$

Which of the following is true for a photochemical reaction?
