Question

The proposed mechanism for a reaction is

Answer 1

Answer: Option (2) is the correct answer.

Explanation:

Rate law is defined as the function of concentration of reactants in a chemical reaction. Rate law of a reaction depends on the slow step of a chemical reaction.

For example, $ClO^{-}(aq) + H_{2}O(l) \rightarrow HClO(aq) + OH^{-}(aq)$ is a slow step reaction.

Therefore, its rate law will be expressed as follows.

        Rate law = $k[ClO^{-}][H_{2}O]$

Thus, we can conclude that out of the given options $k[ClO^{-}][H_{2}O]$ would be a rate law for the given reaction.
