The linear form of the Arrhenius equation is very useful, as a plot of ________ allows us to calculate the activation energy and the frequency factor.

Question

Quizplus · Accepted Answer

The linear form of the Arrhenius equation is ln(k) = -Ea/RT + ln(A), where k is the rate constant, Ea is the activation energy, T is the temperature in Kelvin, R is the gas constant, and A is the frequency factor. A plot of ln(k) versus 1/T gives a straight line with slope of -Ea/R and y-intercept of ln(A). Therefore, by using this plot, we can calculate both the activation energy and the frequency factor.
