    Will the dissociation of\[PC{{l}_{5}}\]in the reaction \[PC{{l}_{5}}(g)PC{{l}_{3}}(g)+C{{l}_{2}}(g);\Delta H=+2.22\]Kcal be favoured by

    A)  increasing temperature

    B)  increasing pressure

    C)  adding more \[PC{{l}_{3}}\]

    D)  adding more\[C{{l}_{2}}\]

    Correct Answer: A

    Solution :

    : As the reaction is endothermic and accompanied by an increase in volume, according to Le Chateliers principle favourable conditions for dissociation of\[PC{{l}_{5}}\]is increase in temperature and decrease in pressure.
