Vedclass · Answer

(B) According to Le Chatelier's principle,an increase in temperature favours the endothermic direction of a reaction. An endothermic reaction is one where heat is absorbed,represented by a negative enthalpy change or a negative heat term on the product side (or positive on the reactant side). In option $B$,the reaction $N_{2(g)} + O_{2(g)} \rightleftharpoons 2NO_{(g)} - 42.8 \ kcal$ can be rewritten as $N_{2(g)} + O_{2(g)} + 42.8 \ kcal \rightleftharpoons 2NO_{(g)}$. Since heat is absorbed in the forward direction,an increase in temperature will shift the equilibrium towards the forward direction.

Which among the following reactions is favoured in the forward direction by an increase in temperature?
