Calculate activation energy from experimental rate constants using the Arrhenius equation. Get accurate Ea values for chemical kinetics analysis, catalyst studies, and reaction optimization.
Calculate the activation energy (Ea) of a chemical reaction using rate constants measured at different temperatures.
k = A Ć e^(-Ea/RT)
Ea = R Ć ln(kā/kā) Ć (1/Tā - 1/Tā)ā»Ā¹
Where R is the gas constant (8.314 J/molĀ·K), kā and kā are rate constants at temperatures Tā and Tā (in Kelvin).
