Molar Difference in Activation Energy

Formula Used

The molar difference in activation energy represents the energetic offset between two distinct reaction pathways or states. In direct mode, the fundamental formula is:

$$\Delta E_a = |E_{a1} - E_{a2}|$$

When evaluated through kinetic rate constants via the Arrhenius equation framework, the relationship connects temperature, rate constants, and the universal gas constant ($R = 8.314 \text{ J/(mol}\cdot\text{K)}$):

$$\ln\left(\frac{k_2}{k_1}\right) = \frac{E_a}{R} \left(\frac{T_2 - T_1}{T_1 T_2}\right)$$
