0Which statement is correct?
(1) If \( \mathrm{N}_{2} \) is added at equilibrium condition, the equilibrium will shift to the forward direction because according to the \( I^{\text {nd }} \) law of thermodynamics, the entropy must increase in the direction of spontaneous reaction.
(2) The condition for equilibrium is \( 2 \Delta \mathrm{G}_{\mathrm{NH}_{3}}=3 \Delta \mathrm{G}_{\mathrm{H}_{2}} \) \( +\Delta G_{N_{2}} \) where \( G \) is Gibbs free energy per mole of the gaseous species measured at that partial pressure.
(3) Addition of catalyst does not change \( K_{p} \) but changes \( \Delta \mathrm{H} \).
(4) At \( 400 \mathrm{~K} \) addition of catalyst will increase the forward reaction by 2 times while the reverse reaction rate will be changed by 1.7 times.
