    In the reaction, \[{{A}_{2}}(g)+4{{B}_{2}}(g)\]⇌ \[2A{{B}_{4}}(g)\]           \[\Delta H<0\]the formation of \[A{{B}_{4}}\]is will be favoured at  [IIT Screening 1990; MP PET 2004]

    A)                 Low temperature, high pressure

    B)                 High temperature, low pressure

    C)                 Low temperature, low pressure

    D)                 High temperature, high pressure

    Correct Answer: A

    Solution :

                    According to Le-Chatelier principle exothermic reaction is forwarded by low temperature, in forward direction number of moles is less, hence pressure is high.
