Arrhenius proposed the equation shown below that relates the rate constant, k , to the energy of activation, E_a, and the absolute temperature given in Kelvin degrees. k = Ae^{( - Ea/RT)} Which statement below is best regarding how the rate constant is related to E_a and the temperature?

According to the Arrhenius equation, the rate constant is proportional to the exponential of (-Ea/RT), where Ea is the energy of activation, R is the gas constant, and T is the absolute temperature. As the temperature increases, the exponential term decreases, leading to an increase in the rate constant. Similarly, as the energy of activation decreases, the exponential term decreases, leading to an increase in the rate constant. Therefore, the rate constant is largest at relatively higher temperatures and when the reaction has an inherently small energy of activation, which is option D.
