Question

Assertion: The overall rate of a complex reaction is governed by the rate of the slowest elementary step.

Reason: All the elementary steps have to wait for the occurrence of the slowest step and the rate of overall reaction cannot exceed the rate of the slowest step.

पर्याय

• If both Assertion and Reason are CORRECT and Reason is the CORRECT explanation of the Assertion.

• If both Assertion and Reason are CORRECT but Reason is not the CORRECT explanation of the Assertion.

• If Assertion is CORRECT but Reason is INCORRECT.

• If Assertion is INCORRECT but Reason is CORRECT.

Answer 1

If both Assertion and Reason are CORRECT and Reason is the CORRECT explanation of the Assertion.

Explanation:

In a complex reaction, the overall rate depends on the slowest elementary step, called the rate-determining step. Since faster steps must wait for the slowest step to occur, the overall reaction cannot proceed faster than this step. Hence, the reason correctly explains the assertion.
