    The units for the equilibrium constant for the reaction \[{{N}_{2}}(g)+3{{H}_{2}}(g)\rightleftharpoons 2N{{H}_{3}}(g)\]are:

    A)  \[at{{m}^{-2}}\]                              

    B)  \[at{{m}^{-1}}\]              

    C)         \[atm\]                               

    D)         \[at{{m}^{2}}\]

    Correct Answer: A

    Solution :

    \[{{N}_{2}}(g)+3{{H}_{2}}(g)\rightleftharpoons 2N{{H}_{3}}(g)\] Here,     \[\Delta \,{{n}_{g}}=2-4=(-\,2)\] Hence, unit, of \[{{K}_{p}}={{(atm)}^{\Delta {{n}_{g}}}}=at{{m}^{-2}}\]
