The reaction (g) (g) (g) N O 2NO is endothermic. The forward reaction is (BHU 2003)

According to the Le-Chatelier’s principle, for an endothermic reaction, with the increase in the temperature, the reaction is favoured in the forward reaction. And with the increase in pressure, the reaction is favoured in the direction where lesser number moles are present. Since, in the given reaction, number of moles of reactant and product are equal. So, there won’t be any change in the equilibrium of the reaction on changing the pressure.
