3H\(_{2(g)}\)+ N\(_{2(g)}\)⇔ 2NH\(_{3(g)}\) ; H= -ve

In the reaction above, lowering of temperature will

  • A have no effect on the equilibrium position
  • B increase the rate of both the forward and reverse reactions equally
  • C favour the forward reaction
  • D favour the reverse reaction

The correct answer is C. favour the forward reaction

N\(_{2(g)}\) + 3H\(_{2(g)}\) ⇔ 2NH\(_{3(g)}\) In the Haber process, the forward reaction is exothermic and the backward reaction is endothermic. If the temperature is decreased, the yield from the exothermic direction is increased i.e. the forward reaction is increased.
