The Arrhenius equation shows the relationship between the rate constant k and the temperature Tin kelvins and is typically written as k=Ae−Ea/RT where R is the gas constant (8.314 J/mol⋅K), Ais a constant called the frequency factor, and Ea is the activation energy for the reaction. However, a more practical form of this equation is lnk2k1=EaR(1T1−1T2) which is mathmatically equivalent to lnk1k2=EaR(1T2−1T1) where k1 and k2 are the rate constants for a single reaction at two different absolute temperatures (T1and...
