    The reaction\[A\xrightarrow{{}}B\]follows a second order kinetics. Doubling the concentration of A will increase the rate of formation of B by a factor of:

    A)  2                                            

    B)  \[\frac{1}{2}\]

    C)  4                                            

    D)  \[\frac{1}{4}\]

    Correct Answer: C

    Solution :

                    \[A\xrightarrow[{}]{{}}B\]is a second order reaction. \[\therefore \]  Rate \[(r)=k{{[A]}^{2}}\] Hence, on doubling the concentration of [A] the rate of reaction is increased by four unit.
