What effect does a catalyst have on a system in equilibrium? the forward reaction slows down, and the reverse reaction speeds up. the system is unaffected. the forward reaction is favored. the reverse reaction is favored.

A catalyst is when a chemical reaction occurs faster than normal.

The system is unaffected during a catalyst because both forward and reverse reactions are affected, meaning that quilibrium will occur faster nothing will change.

Hope it helped,
