Question

In many reactions, the reaction proceeds in a sequence of steps. The overall rate of such reactions is determined by ______.

विकल्प

• slowest step

• fastest step

• molecularity of the steps

• order of different steps

Answer 1

In many reactions, the reaction proceeds in a sequence of steps. The overall rate of such reactions is determined by slowest step.

Explanation:

In reactions that proceed through multiple steps, one step is usually slower than the others. This slowest step acts as a bottleneck and determines the overall rate of the reaction. It is known as the rate-determining step (RDS).
