Webtemperature and is given by the Arrhenius equation: ⋅ ⋅ (11) where k0 is a pre-exponential factor, Ea is the activation energy for the reaction, and T is the absolute tempera-ture. The reaction order and rate constant can be determined by the integral method of analysis. In this method, the WebThe curve’s peak represents the transition state. We can use the Arrhenius equation to relate the activation energy and the rate constant, k, of a given reaction: k = Ae−Ea/RT k = A e − E a / R T. In this equation, R is the ideal gas constant, which has a value 8.314 J/mol/K, T is temperature on the Kelvin scale, Ea is the activation ...
