How will a catalyst affect the position of equilibrium?

A catalyst is something that speeds up the rate of reaction, without being consumed during the reaction. If a catalyst is used in a reaction, it will only speed up the forward and backward reaction, however the equilibrium position remains unchanged/constant. For example, in the Haber process for the synthesis of ammonia, introducing a catalyst will only increase the rate of the reaction, however the position of the equilibrium will not change.
