Question

In industrial synthesis of NH₃ (Haber process), a catalyst is used because:
  1. A
    It increases Kc
  2. B
    It shifts equilibrium to right
  3. C
    It speeds up equilibrium attainment without changing K
    Correct
  4. D
    It increases pressure

Correct answer

It speeds up equilibrium attainment without changing K

Explanation

The iron catalyst in the Haber process lowers activation energy for both forward and reverse reactions, speeding up equilibrium attainment. K is unchanged.
