    It has been found that for a chemical reaction with rise in temperature by\[{{10}^{o}},\]the rate constant is                                     

    A)  nearly doubled    

    B)  nearly tripled

    C)  increases 5 times  

    D)  increases 4 times

    Correct Answer: A

    Solution :

     Rate constant of a chemical reaction depends strongly on temperature. According to a rough rule, valid for many reactions in solution, at near room temperature, rate constant (k) doubles for each \[\text{10}{{\,}^{\text{o}}}\text{C}\]rise in temperature.
