NEET Chemistry Rate of Reaction Assertion Reason Question
Assertion (A): The rate constant of a first-order reaction is independent of the initial concentration of the reactants.
Reason (R): The half-life of a first-order reaction is directly proportional to the initial concentration of the reactants.
Both (A) and (R) are true, and (R) is the correct explanation of (A).
Both (A) and (R) are true, but (R) is not the correct explanation of (A).
(A) is true, but (R) is false.
(A) is false, but (R) is true.
Correct Answer
Detailed Explanation
The rate constant of a first-order reaction is indeed independent of the initial concentration, while the half-life is constant and not proportional to initial concentration, contradicting the reason.
