Reverse Activation Energy Calculator:
Enter the values of Forward Activation Energy FAE(J) & Change in Enthalpy dH(J/mol) to determine the value of Reverse Activity Energy RAE(J).
Reverse Activation Energy Formula:
The Reverse Activation Energy RAE(J) in Joules is equal to the Forward Activation Energy FAE(J) in Joules and is subtraction by the Change in Enthalpy dH(J/mol) in Joules per mole.
The formula of Reverse Activation Energy Can be written as,
RAE(J) = FAE(J) – Dh(J/mol)
Here,
RAE(J) = Reverse Activity Energy in Joules
FAE(J) = Forward Activation Energy in Joules
dH(J/mol) = Change in Enthalpy in Joules per mole
Reverse Activation Energy Calculation:
1) Calculate the Reverse Activation Energy and given for the Forward Activation Energy = 30 Joules, Change in Enthalpy = 4J/mol.
Answer
RAE = FAE – dH
RAE = 30 – 4
RAE = 26 Joules.
2) CalculateThe Forward Activation Energy and given For the Reverse Activity Energy = 26 Joules, Change in Enthalpy = 4 J/mol.
Answer
RAE = FAE – dH
26 = FAE – 4
FAE = 26 + 4
FAE = 30 Joules.
