    When heated, ammonium carbamate decomposes as follows: \[N{{H}_{4}}COON{{H}_{2}}(s)\rightleftharpoons 2N{{H}_{3}}(g)+C{{O}_{2}}(g)\]. At a certain temperature, the equilibrium pressure of the system is 0.318 atm. \[{{K}_{p}}\] for the reaction is:

    A) 0.128               

    B) 0.426

    C) \[4.76\times {{10}^{-3}}\]       

    D) None of these

    Correct Answer: C

    Solution :

    [c] \[{{P}_{total}}=3P\] \[\Rightarrow P=\frac{0.318}{3}=0.106\] \[\therefore {{K}_{p}}=4{{P}^{3}}=4.76\times {{10}^{-3}}\]
