    In the reaction\[{{H}_{2}}(g)+C{{l}_{2}}(g)\rightleftharpoons 2HCl(g)\]

    A) \[{{K}_{p}}\ne {{K}_{c}}\]

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

    C)  \[{{K}_{p}}>{{K}_{c}}\]

    D)  \[{{K}_{p}}<{{K}_{c}}\]

    Correct Answer: B

    Solution :

     \[{{H}_{2}}(g)+C{{l}_{2}}(g)2HCl(g)\] We know that, \[{{K}_{p}}={{K}_{c}}.{{(RT)}^{\Delta {{n}_{g}}}}\] \[\Delta {{n}_{g}}=\]no. of moles of gaseous products - no. of moles of gaseous reactants \[=2-2=0\] \[{{K}_{p}}={{K}_{c}}.{{(RT)}^{o}}\] \[{{K}_{p}}={{K}_{c}}\]
