JEE Main & Advanced Chemistry Chemical Kinetics Question Bank Rate of a reaction

  • question_answer The temperature coefficient of a reaction is

    A)                 Specific reaction rate at \[{{25}^{o}}C\]

    B)                 Rate of the reaction at \[{{100}^{o}}C\]

    C)                 Ratio of the rate constants at temperatures \[{{35}^{o}}C\] and \[{{25}^{o}}C\]

    D)                 Ratio of the rate constants at two temperatures differing by \[{{1}^{o}}C\]

    Correct Answer: C

    Solution :

                    Temperature coefficient \[\frac{{{K}_{\text{3}{{\text{5}}^{\text{o}}}C}}}{{{K}_{{{25}^{o}}C}}}=\frac{{{K}_{308k}}}{{{K}_{298k}}}=2\] and 3 for most reactions.
