    Given reaction is \[2{{X}_{(gas)}}+{{Y}_{(gas)}}\] ⇌ \[2{{Z}_{(gas)}}+80\,kcal\] Which combination of pressure and temperature gives the highest yield of Z at equilibrium         [NCERT 1979]

    A)                 1000 atm and \[{{500}^{o}}C\]

    B)                 500 atm and \[{{500}^{o}}C\]

    C)                 1000 atm and \[{{100}^{o}}C\]

    D)                 500 atm and \[{{100}^{o}}C\]

    Correct Answer: C

    Solution :

              The reaction takes place with a reduction in number of moles (volume) and is exothermic. So high pressure and low temperature with favour the reaction in forward direction
