    The conversion of A to B follows second order kinetics. Doubling the concentration of A will increase the rate of formation of B by a factor of:

    A)  \[4\]              

    B)  \[2\]

    C)  \[1/4\]          

    D)  \[1/2\]

    Correct Answer: A

    Solution :

    Conversion of \[A\xrightarrow{{}}B\] follows second order kinetics therefore, \[r=K{{[A]}^{2}}\] The concentration is doubled \[r=K{{[2A]}^{2}}=K4{{[A]}^{2}}\] Therefore, the new rate becomes four times.
