    For the reaction, \[PC{{l}_{3(g)}}\]+\[C{{l}_{2(g)}}\]⇌\[PC{{l}_{5(g)}}\], the value of \[{{K}_{c}}\] at 250°C is 26. The value of \[{{K}_{p}}\] at this temperature will be [UPSEAT 1999, 2000, 02]

    A)                 0.61       

    B)                         0.57

    C)                 0.83       

    D)                 0.46

    Correct Answer: A

    Solution :

               \[{{K}_{p}}={{K}_{c}}{{[RT]}^{\Delta n}};\,\,\Delta n=-1,\,\,{{K}_{c}}=26\]                    \[R=0.0812,\,T=250+273=523K\]                                 \[{{K}_{p}}=26{{[0.0812\times 523]}^{-1}}=0.605\approx 0.61\]
