NEET Chemistry Rate of Reaction Assertion Reason Question
Assertion (A): The rate constant of a reaction is independent of the concentration of reactants. | Reason (R): For a first order reaction, the rate constant can be calculated using the concentration of the reactants at different times.
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.
Correct Answer
Detailed Explanation
While the rate constant is indeed independent of reactant concentrations, the Reason provided is not the correct explanation for the Assertion. The rate constant calculation for a first order reaction uses concentrations at different times but this does not explain the independence from concentration.
