Raquel is a little off there. When you add a catalyst it will definitely not increase the activation energy of a forward reaction. Adding a catalyst will decrease the activation energy both in the forward direction and the backward direction. When this happens the rate of the reaction will increase both in the forward and in the backward direction. None of those answers should be “not affected”

A catalyst would speed up OR decelerate a reaction via reducing the activation capability required. In for this reason way it supplies an determination pathway. For a reaction to ensue a collision ought to take place with the superb option orientation and sufficiant capability. In a substance the molecules have one in each and every of those tiers of kinetic capability. A catalyst means greater collisions take place on the superb option orientation (brings them mutually is sturdy way) and sufficiant eneregy (and not as plenty is needed) meaning that the reaction is accelerated.

Rates are increased, activation energies are decreased

Thank you for clarifying
