The linear form (plot of ln k vs.1/T) of the Arrhenius equation is very useful, as it allows us to calculate the activation energy from the _______ and the frequency factor from the _______ .

Question

Quizplus · Accepted Answer

The linear form of the Arrhenius equation is ln k = ln A - Ea/R(1/T), where k is the rate constant, A is the frequency factor, Ea is the activation energy, R is the gas constant, and T is the temperature in Kelvin. The slope of this plot is -Ea/R, which allows calculation of the activation energy, and the intercept is ln A, from which the frequency factor can be calculated.
