  • question_answer
    For the reaction \[{{N}_{2(g)}}+{{O}_{2(g)}}\] ⇌\[2N{{O}_{(g)}}\], the value of \[{{K}_{c}}\] at \[{{800}^{o}}C\] is 0.1. When the equilibrium concentrations of both the reactants is 0.5 mol, what is the value of \[{{K}_{p}}\] at the same temperature      [KCET 2005]

    A)                 0.5         

    B)                 0.1

    C)                 0.01       

    D)                 0.025

    Correct Answer: B

    Solution :

               \[{{N}_{2(g)}}+{{O}_{2(g)}}\] ⇌\[2N{{O}_{(g)}}\]                    \[{{K}_{c}}=0.1,\,{{K}_{p}}={{K}_{c}}{{(RT)}^{\Delta n}}\]                                 \[\Delta n=0,\,{{K}_{p}}={{K}_{c}}=0.1\]
