    For reaction\[3X+Y{{X}_{3}}Y\]\[\Delta H=+ve\], amount of \[{{X}_{3}}Y\] can be changed by:

    A)  changing temperature

    B)  changing pressure

    C)  changing temperature, pressure,

    D)  changing temperature, pressure, adding catalyst

    Correct Answer: C

    Solution :

    Given\[3X+Y{{X}_{3}}Y-Q\,\,cal\]. According to Le-Chatelier principle amount of \[{{X}_{3}}Y\] can be changed by changing temperature because reaction is endothermic and it can be changed by changing in pressure because number of moles of reactant and products are different. But can never change by adding catalyst because the above example is  reversible reaction.
