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

Silver nitrate is usually kept in coloured bottles because it is

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

The law of photochemical equivalence was given by

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

Which of the following is true for a photochemical reaction?
