Seems intuitive that it wouldn’t, but I dunno the qualitative difference between activation energy & Gibbs free energy.
I’M TOO LAZY TO GOOGLE
I GOTS STUFF TO DO
Best reply by BlueWolf:
A catalyst can change the activation energy not the Gibbs energy. The Gibbs energy is the energy difference between the initial state and final state. A catalyst cannot change that. Imagine you are driving from school to home. How you drive do not change the height difference between the school and your home. However, a catalyst can change your path which can change the routine you drive from school to home. So if there is a hill in between your school and you home, you have the choice to drive through it or drive around.
Here is a picture:
A catalyst can change the height of the barrier, but cannot alter the initial or final state.
