                    For a reversible reaction, if the concentrations of the reactants are doubled, the equilibrium constant will be:

    A)                                                                                                                                                                                                         one-fourth 

    B)                 halved 

    C)                 doubled 

    D)                 the same

    Correct Answer: D

    Solution :

                    Consider a hypothetical change                 \[A+B\rightleftharpoons C+D\]                 For this reaction,                 \[{{K}_{eq}}.=\frac{[C]\,[D]}{[A]\,[B]}\]                 For the above reaction if concentration of reactants are doubled than the rate of forward reaction increases for a short time but after sometime equilibrium will established. So, concentration has no effect on equilibrium constant. It remains unchanged after increasing the concentration of reactants.
