    In the given reaction,\[2X(g)+Y(g)\rightleftharpoons 2Z(g)+80\,kcal.\] Which combination of pressure and temperature will give the highest yield of Z at equilibrium?

    A)  1000 atm and \[200{}^\circ C\]

    B)  500 atm and \[500{}^\circ C\]

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

    D)  500 atm and \[100{}^\circ C\]

    E)  1000 atm and \[500{}^\circ C\]

    Correct Answer: C

    Solution :

                    In this equation, volume is decreasing and the reaction is exothermic, So, for the highest yield of Z, pressure should be high and temperature should be low.
