Vedclass · Answer

(D) According to Le Chatelier's Principle,for an equilibrium reaction,decreasing the temperature favours the direction that releases heat (exothermic reaction).An exothermic reaction is characterized by a negative enthalpy change,i.e.,$\Delta H^o Let us analyze the given reactions:$(a) \ \Delta H^o = 181 \ kJ$ (Endothermic)$(b) \ \Delta H^o = 566 \ kJ$ (Endothermic)$(c) \ \Delta H^o = -9.4 \ kJ$ (Exothermic)$(d) \ \Delta H^o = -541 \ kJ$ (Exothermic)Since reactions $(c)$ and $(d)$ are exothermic,decreasing the temperature will shift the equilibrium towards the products,thereby favouring product formation.
