AIt pushes the mixture past the equilibrium
BIt brings the equilibrium about more rapidly
CIt holds the mixture short of the equilibrium
DIt converts the reaction into a one way change
Answer & Solution
Correct answer: B. It brings the equilibrium about more rapidly
1. Part of the rate lost by running a process cool can be recovered with a catalyst.
2. The catalyst raises the rate of both directions, so the mixture arrives at balance sooner.
3. The composition at that balance point is the same as it would be without the catalyst.
4. Nothing can push a closed system past its equilibrium, so that option is impossible.
