    Hydrocarbon on reaction with steam produces hydrogen gas. Chemical reaction occuring in this process is given by \[{{\operatorname{H}}_{2}}O\,(g)+C{{H}_{4}}(g) \,\rightleftharpoons \,\,CO\,(g)\,+\,3{{H}_{2}}\,(g)\] If \[{{\operatorname{K}}_{C}}=3.0\times 1{{0}^{-}}^{4}\] at 1000 K, then the \[{{K}_{p}}\] would be

    A)  202                             

    B)  2.02               

    C)  20.2                            

    D)  0.6740

    Correct Answer: B

    Solution :

    \[\Delta n-\left( 3+1 \right)-2= 2\] \[{{K}_{p}}={{K}_{c}}{{(RT)}^{\Delta n}}\] \[=3\times {{10}^{-\,4}}\,{{(0.0821\times 1000)}^{2}}\] \[=\,\,\,3\times 6740.41 \times 1{{0}^{-}}^{4}\] \[= \,3 \times \,.\,6740 = 2.02\]
