What does a catalyst not affect?
AElevated compression
BEquilibrium composition
CEqual concentration only
DEffective collision only
Answer & Solution
Correct answer: B. Equilibrium composition
1. A catalyst speeds both directions identically.
2. The balance point is therefore untouched.
3. Catalyst does not affect the equilibrium composition of a reaction mixture.
4. So the answer is the equilibrium composition.
