Reverse Activation Energy Calculator

Formula

The formula to calculate Reverse Activation Energy (RAE) is:

\[ RAE = FAE - dH \]

Where:

\( RAE \) is the Reverse Activation Energy (J)
\( FAE \) is the Forward Activation Energy (J)
\( dH \) is the Change in Enthalpy (J/mol)

What is Reverse Activation Energy?

Reverse activation energy is the energy required to initiate the reverse reaction in a chemical process. It is calculated by subtracting the change in enthalpy from the forward activation energy. This concept is essential in understanding the dynamics of reversible reactions and the energy barriers involved.

Example Calculation

Let's consider an example:

Forward Activation Energy (FAE): 100 kJ
Change in Enthalpy (dH): 50 kJ/mol

Using the formula to calculate the Reverse Activation Energy:

\[ RAE = 100 - 50 = 50 \, \text{kJ} \]

This demonstrates that with a forward activation energy of 100 kJ and a change in enthalpy of 50 kJ/mol, the reverse activation energy would be 50 kJ.
