    If the equilibrium concentration of A is doubled in the following equilibrium \[A{{B}_{2}}(s)A(g)+{{B}_{2}}(g)\]the equilibrium concentration of \[{{B}_{2}}\] would be

    A)  one fourth of initial concentration

    B)  half of the initial concentration

    C)  doubled

    D)  same as initial concentration

    Correct Answer: B

    Solution :

                     For the reaction                 \[A{{B}_{2}}(s)A(g)+{{B}_{2}}(g)\]                                 \[{{K}_{c}}=[A]\,\,[{{B}_{2}}]\] If the equilibrium concentration of A is doubled then the equilibrium concentration of \[{{B}_{2}}\] should be halved of the initial concentration to maintain the constant value of \[{{K}_{c}}\].
