How does a catalyst affect the position of a chemical equilibrium?

Answer

It does not shift the equilibrium position, only the time taken to reach it

A catalyst speeds up both the forward and the reverse reactions equally by lowering the activation energy for both directions. Therefore, the final ratio of products to reactants at equilibrium, governed by Gibbs Free Energy change ($\Delta G$), is unaffected.
