  • question_answer
    For the reaction \[{{H}_{2}}(g)+{{I}_{2}}(g)\]⇌ \[2HI(g)\] at \[721K\] the value of equilibrium constant \[({{K}_{c}})\] is 50. When the equilibrium  concentration of both is \[0.5\,M\], the value of \[{{K}_{p}}\] under the same conditions will be                 [CBSE PMT 1990]

    A)                 0.002    

    B)                 0.2

    C)                 50.0       

    D)                 \[50/RT\]

    Correct Answer: C

    Solution :

           For the reaction \[{{H}_{2}}+{{I}_{2}}\] ⇌ 2HI            \[\Delta n=0\]                                 So \[{{K}_{p}}={{K}_{c}}\]  \50.0
