Vedclass · Answer

(D) catalyst is a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change. $1.$ It provides an alternative pathway for the reaction with lower activation energy $(E_a)$. $2.$ By lowering the activation energy,it allows more reactant molecules to cross the energy barrier,thereby increasing the reaction rate. $3.$ Consequently,the system reaches the state of chemical equilibrium in a shorter amount of time. Therefore,both statements regarding time and activation energy are correct.
