where Ea is the activation energy of the reaction (cal/mol), R is
the ideal gas constant (1.986 cal/mol K), T is the absolute temperature
(K), and A0 is the pre-exponential constant. A plot of the
log of rate constant for the test temperature versus the reciprocal
of the absolute temperature gives the straight line if the Arrhenius
relation is applied to the specific reaction. The energy of the activation
(Ea) was derived from the slope (Ea/R). The intercept, however,
gives the exponential constant. To study the influence of temperature
on reaction rate, the Q10 values were calculated according to
the following relationship:
