Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
A catalyst influences the rate of forward and backwards reaction equally. It lowers the activation energy required to reach equllibirium but does not influence the equilibirium constant.

Assertion (A) The enthalpy of reaction remains constant in the presence of a catalyst.

Reason (R) A catalyst participating in the reaction forms different activated complex and lowers down the activation energy but the difference in enrgy of reactant and product remains the same.
