And the first step in this reaction is the rate- limiting step, the overall rate of reaction is first- order in both. Apr 22, · A look at the arrhenius equation to show how rate. You probably remember from CHM1045 endothermic and exothermic reactions: In order to calculate the activation energy we need an equation that relates the rate constant of a reaction with the temperature ( energy). If the reaction is first order it. A second- order reaction was observed. Before going on to the Activation Energy, let' s look some more at Integrated Rate Laws. The Activation Energy ( E a) - is the energy level that the reactant molecules must overcome before a reaction can occur. We need to look at what actually happens to reactant molecules during a chemical reaction. Question: You wish to determine the activation energy for the following first- order reaction. To associating this activation energy with the threshold barrier for an elementary reaction. This example problem demonstrates how to determine the activation energy of a reaction from reaction rate constants at different temperatures. Activation energies of the forward reaction.
