Chemical Kinetics - Result Question 34

####34. If $I$ is the intensity of absorbed light and $C$ is the concentration of $A B$ for the photochemical process. $A B+h \nu \rightarrow A B^{}$, the rate of formation of $A B^{}$ is directly proportional to

$(2001,1 M)$

(a) $C$

(b) $I$

(c) $I^{2}$

(d) $C \cdot I$

Show Answer

Answer:

Correct Answer: 34. (c)

Solution:

  1. Rate will be directly proportional to both concentration and intensity, i.e. rate of formation of $A B^{*} \propto C \cdot I$.
