Problem

Given below are two statements Statement I: For the reaction in equilibrium, N2(g)+3H2(g)⇌2NH3(g);ΔrH=−ve,\text{N}_2(\text{g}) + 3\text{H}_2(\text{g}) \rightleftharpoons 2\text{NH}_3(\text{g}); \Delta_r H = -ve, reaction is favoured in backward direction by low pressure, high temperature and high concentration of ammonia. Statement II: For the reaction in equilibrium 2NO2(g)⇌N2O4(g);ΔrH=−ve,2\text{NO}_2(\text{g}) \rightleftharpoons \text{N}_2\text{O}_4(\text{g}); \Delta_r H = -ve, dimerization of NO2_2(g) is favoured by high pressure and low temperature. In the light of above statements, choose the correct answer from the options given below.
