### Catalysts and equilibrium constant

Would the equilibrium become greater in the presence of a catalyst?

I'm not too sure what you mean by equilibrium, but a catalyst speeds up a reaction by lowering activation energy. If the reaction is at equilibrium, I think the equilibrium constants don't change if you add a catalyst.

Sorry, equilibrium constant*

Since catalysts speed up forward and reverse reactions to the same extent, the addition of a catalyst should not affect equilibrium constant.

A catalyst just provides a different pathway for the reaction to occur at a lower activation energy, this will not affect the value of the equilibrium constant.
