How does the equilibrium constant for a reaction change when a catalyst is added?
A.It does not change
B.It increases
C.It decreases
D.It becomes zero
Explanation
Core Concept
A catalyst lowers the activation energy of both directions equally, so forward and reverse rates scale together and the balance point — K — stays fixed.
Correct Answer
AIt does not change
