    If pressure increases then its effect on given  equilibrium \[2NO(g){{N}_{2}}(g)+{{O}_{2}}(g)\] is shift in:

    A) forward direction

    B) backward direction

    C) no effect

    D) none of the above

    Correct Answer: C

    Solution :

    Key Idea: According to Le-Chatelier principle the reactions in which number of moles of readouts is equal to number of moles of products, is not effected by change in pressure. \[2\,NO\,(g){{N}_{2}}(g)+{{O}_{2}}(g)\]                 Moles of reactants \[=2\]                 Moles of product \[=2\] \[\because \]There is no change in number of moles of reactants and products. \[\therefore \]The reaction is not effected by change in pressure.
