What is the effect of a catalyst in an equilibrium process?

A catalyst provides an alternative pathway for a reaction to take place and therefore helping the reaction to take place at a lower activation energy. In an equilibrium process, a catalyst has no effect on the position of equilibrium. All it does is allow the reaction to reach equilibrium at a faster rate, but does not have any effect on the position of equilibrium. As always, the catalyst is not changed in the reaction.
