  • question_answer
    For a reaction \[A\to B\], the rate of reaction quadrupled when the concentration of A is doubled. The rate expression of the reaction is  \[r=K{{(A)}^{n}}\]. when the value of \[n\] is

    A)                 1             

    B)                 0

    C)                 3             

    D)                 2

    Correct Answer: D

    Solution :

                    Rate of reaction is quadrupled on doubling the concentration. Thus \[r\propto \,{{[A]}^{2}}\].
