    In which of the following reactions, the concentration of reactant is equal to concentration of product at equilibrium: (K = equilibrium constant)

    A)  \[AB;K=0.01\]

    B)  \[RP;K=1\]

    C)  \[XY;K=10\]

    D)  \[LJ;K=0.025\]

    Correct Answer: B

    Solution :

                     Concentration of reactant and product becomes equal at equilibrium only when the value of equilibrium constant is one. \[\underset{(R)}{\mathop{\text{Reactant}}}\,\underset{(P)}{\mathop{\text{Product}}}\,\] \[{{K}_{c}}=\frac{[Product]}{[Reactant]}\] If the concentration of both reactants and products becomes equal, then the value of \[{{K}_{c}}=1.\]
