प्रश्न
Assertion (A): For a zero-order reaction, the unit of rate constant and rate of reaction are same.
Reason (R): Rate of reaction for zero order reaction is independent of concentration of reactant.
विकल्प

उत्तर
Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).
Explanation:
The rate of zero-order reaction does not depend on the concentration of the reactant. As a result, the unit for both rate of reaction and rate is the same.
