# Given the following Assertion and Reason, which of the following statements is true?

Assertion:A catalyst increases the rate of the $Rx^n$.

Reason : A catalyst increases the energy of product and decreases of the reactions.

$\begin{array}{1 1}(a)\;\text{Assertion is correct reason is correct explanation of assertion}\\(b)\;\text{Assertion is correct reason is not correct explanation of assertion}\\(c)\;\text{Assertion is not correct reason is correct}\\(d)\;\text{Assertion is correct reason is incorrect}\end{array}$

A catalyst provide alternative path to the $Rx^n$ with out changing the energy of reactant or product.
Hence (d) is the correct answer.
