  • question_answer If \[{{K}_{p}}\] for a reaction \[{{A}_{(g)}}+2{{B}_{(g)}}3{{C}_{(g)}}+{{D}_{(g)}}\] is \[0.05\] atm at \[1000K.\] Its \[{{K}_{C}},\] in terms of R will be

    A)  \[20000\text{ }R\]                  

    B)  \[0.02\text{ }R\]

    C)  \[5\times {{10}^{-5}}\,R\]              

    D)  \[\frac{5\times {{10}^{-5}}}{R}\]

    Correct Answer: D

    Solution :

    \[{{\Delta }_{ng}}=4-3=1\] \[{{K}_{p}}={{K}_{C}}\,{{(RT)}^{\Delta n}}\] \[0.05={{K}_{C}}\,(1000\,R)\]                 or            \[{{K}_{C}}\,\frac{5\times {{10}^{-5}}}{R}\]
