Statement I : Introduction of catalyst does not affect position of equlibrium

Statement II : For a reversible reaction, presence of a catalyst influences both forward & backward reaction to the same extent

A catalyst does not affect the extent of the process (position of equilibrium) under a given set of conditions. However, a catalyst improves the rate of attainment of equilibrium. This is because a catalyst lowers the activiation energy of both forward and backward process equally.Attains dynamic nature quickly.
