For the reaction N₂_(g) + 3H₂_(g) ⇌ 2NH₃_(g) ;
which of the following is correct?

Addition of a catalyst does not change K_p but changes ΔH

On addition of N₂, the equilibrium will shift in the forward direction because according to second law of thermodynamics the entropy increases in the direction of spontaneous reaction.

At 298 K, addition of a catalyst increases the rate of both forward and backward reaction by a factor of two. But at 400 K, the same catalyst increases the rate of forward reaction by a factor of two and that of backward reaction by a factor of 1.7 .

At equilibrium, G_N₂ + 3G_H₂ = 2G_NH₃ where G is the molar Gibbs free energy.
