Question

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): The quantum yield of a photochemical reaction can be greater than one.
Reason (R): A single photon can initiate chain of reactions, leading to the conversion of multiple reactant molecules.
In the light of the above statements, choose the most appropriate answer from the options given below :

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A)
• B. Both (A) and (R) are correct but (R) is not the correct explanation of (A)
• C. (A) is correct but (R) is not correct
• D. (A) is not correct but (R) is correct

Hint:

Quantum yield > 1 occurs in chain reactions due to propagation steps.

Answer 1

The Correct Option is A
