WebThe 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. WebThe Arrhenius equation allows us to calculate activation energies if the rate constant is known, or vice versa. As well, it mathematically expresses the relationships we established earlier: as activation energy term Ea increases, the rate constant k decreases and therefore the rate of reaction decreases.

Activation Energy and the Arrhenius Equation – Introductory Chemistry

WebNov 29, 2024 · Things You Should Know. Use the Arrhenius equation as your starting point for calculating activation energy: k = Ae^ (-E_a/RT). Rearrange the equation to E_a = -R * T * ln (k/A) if you’re given one temperature reading and the pre-exponential factor. Adjust the equation to E_a = R * ln (k_1/k_2) / (1/T_2 - 1/T_1) if you’re given two ...
