    For the equilibrium,\[2N{{O}_{2}}(g)\rightleftharpoons {{N}_{2}}{{O}_{4}}(g)+14.6\,\,\text{kcal,}\]increase in temperature

    A)  favours the formation of\[{{N}_{2}}{{O}_{4}}\]

    B)  favours the decomposition of\[{{N}_{2}}{{O}_{4}}\]

    C)  does not affect equilibrium

    D)  stop the reaction

    Correct Answer: B

    Solution :

                    The given reaction is exothermic and according to Le-Chatelier principle high temperature shifts the equilibrium in backward direction. In other words,   high   temperature   favours   the decomposition of \[{{N}_{2}}{{O}_{4}}\]
