SUMMARY
The discussion centers on the correct formulation of the Arrhenius Equation for calculating activation energy (Ea). Two versions are presented: ln(k2/k1) = -Ea/R * (1/T2 - 1/T1) and ln(k1/k2) = Ea/R * (1/T2 - 1/T1). Both equations are mathematically equivalent due to the properties of logarithms, specifically ln(a/b) = ln a - ln b. Therefore, users can confidently use either version depending on their preference for the sign of Ea.
