    The activation energy for most of the reactions is approximately\[50\text{ }kJ\text{ }mo{{l}^{-1}}\]. The value of temperature coefficient for such reactions is

    A)  >2                                         

    B)  >3

    C)   <1                                        

    D)  >4

    Correct Answer: A

    Solution :

                     The temperature coefficient is the ratio of two velocity constants having the difference of\[10{}^\circ C\]. Temperature coefficient \[=\frac{{{k}_{t}}+10}{{{k}_{t}}}\]For most of the reaction its value lies between 2 and 3.
