Vedclass · Answer

(B) catalyst is a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.In a reversible reaction,a catalyst increases the rates of both the forward and backward reactions to the same extent.This allows the system to reach the state of equilibrium more quickly.However,a catalyst does not alter the position of the equilibrium,nor does it change the thermodynamic properties like the energies of reactants and products.It works by providing an alternative reaction pathway with a lower activation energy.
