    The rate of reaction between \[A\] and \[B\] increases by a factor of 100, when the concentration of \[A\] is increased 10 folds. The order of reaction with respect to \[A\] is [CPMT 1985]

    A)                 10          

    B)                 1

    C)                 4             

    D)                 2

    Correct Answer: D

    Solution :

               \[r=K{{[A]}^{n}},\,\,\,\,100r=K{{[10A]}^{n}}\]                                 Thus \[\frac{1}{100}={{\left( \frac{1}{10} \right)}^{n}}\]or n = 2
