WebAug 18, 2024 · Therefore, to use the Arrhenius equation, we need to first determine the activation energy of the crystal type under test. However, different samples from the same crystal type should have identical activation energies. For example, to obtain the Arrhenius plots in Figure 1, five samples of each crystal type are used. soncy roadWebThe frequency factor, A, in the equation is approximately constant for such a small temperature change. We need to look at how e-(E A / RT) changes - the fraction of molecules with energies equal to or in excess of the activation energy. Let's assume an activation energy of 50 kJ mol-1. In the equation, we have to write that as 50000 J mol-1. soncy road bodyWebIn order to calculate the activation energy we need an equation that relates the rate constant of a reaction with the temperature (energy) of the system.
