    The Arrhenius equation expressing the effect of temperature on the rate constant of a reaction is:

    A)  \[k={{e}^{-E/RT}}\]                       

    B)  \[k=In\frac{E}{RT}\]

    C)  \[k=\frac{A.E}{RT}\]                      

    D)  \[k=A.{{e}^{-Ea/RT}}\]

    Correct Answer: D

    Solution :

                    Arrhenius proposed a quantitative relationship between the rate constant and temperature as: \[K=A{{e}^{-{{E}_{a}}/RT}}\] Where A = frequency factor \[{{E}_{a}}=\]activation energy
