2NH3 Which is correct statement if N2 is added at equilibrium condition?
- The equilibrium will shift to forward direction because according to IInd law of thermodynamics the entropy must increase in the direction of spontaneous reaction.
- The condition for equilibrium is GN2 + 3GH2 = 2GNH3
where G is Gibbs free energy per mole of the gaseous species measured at that partial pressure. The condition of equilibrium is unaffected by the use of catalyst, which increases the rate of both the forward and backward directions to the same extent. - The catalyst will increase the rate of forward reaction by b.
- Catalyst will not alter the rate of either of the reaction.
Answer
(B) The condition for equilibrium is G N 2 + 3 G H 2 = 2 G NH 3 where G is Gibbs free energy per mole of the gaseous species measured at that partial pressure. The condition of equilibrium is unaffected by the use of catalyst, which increases the rate of both the forward and backward directions to the same extent.
