    \[{{H}_{2}}(g)+{{I}_{2}}(g)2HI(g)\] In this reaction when increase pressure the reaction direction is:

    A)  does not change

    B)  forward

    C)  backward     

    D)  decrease          

    Correct Answer: A

    Solution :

    \[{{H}_{2(g)}}+{{I}_{2(g)}}2H{{I}_{(g)}}\] The equilibrium in the formation of \[HI\] from \[{{H}_{2}}\]and 12 is not affected by the increase in pressure because there is no change in the number of moles i.e., the number of moles of reactants and products is the same.
