    The rate of a chemical reaction doubles for every \[\text{10}{{\,}^{\text{o}}}\text{C}\] increase in temperature, if the temperature of reaction is increased from  \[\text{30}{{\,}^{\text{o}}}\text{C}\] to \[\text{80}{{\,}^{\text{o}}}\text{C}\text{.}\] The rate of reaction increases:

    A)  16                                         

    B)  32

    C)  64                                         

    D)  4

    Correct Answer: B

    Solution :

                     Increase in temperature \[=80-30=50{{\,}^{o}}C\]For every \[\text{1}{{\text{0}}^{\text{o}}}\text{C}\] increase in temperature rate of reaction doubles. Thus, for \[\text{50}{{\,}^{\text{o}}}\text{C}\] increase in temperature increase in rate of reaction \[\text{= }{{\text{2}}^{5}}=32\,\text{times}\]
