What is the effect of adding a catalyst to a reversible reaction at equilibrium?
AIt shifts the equilibrium to the right
BIt shifts the equilibrium to the left
CIt speeds up both forward and backward reactions equally
DIt only speeds up the forward reaction
✓ Correct Answer: C — It speeds up both forward and backward reactions equally
A catalyst lowers the activation energy for both directions, so it helps reach equilibrium faster but does not change the position of equilibrium.
