    For a gaseous reversible reaction, which of the following expressions is correct?

    A)  \[{{K}_{c}}={{K}_{p}}{{(RT)}^{\Delta n}}\]           

    B)  \[{{K}_{p}}={{K}_{c}}+\Delta nRT\]

    C)  \[{{K}_{p}}={{K}_{x}}{{(p)}^{\Delta n}}\]             

    D)  \[{{K}_{p}}={{K}_{c}}(RT/\Delta n)\]

    Correct Answer: C

    Solution :

                     For a gaseous reversible reaction, \[{{K}_{p}}={{K}_{c}}{{(RT)}^{\Delta n}}\] \[PV=RT\] At constant volume, \[P=RT\] then,     \[{{K}_{p}}={{K}_{x}}{{(P)}^{\Delta n}}\]
