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, T is the temperature, Ea is the activation energy, R is the gas constant, and A is the frequency factor. Plotting ln(k) vs. 1/T gives a straight line with slope -Ea/R and intercept ln(A), allowing us to calculate both Ea and A. Therefore, choice D, the logarithm of the rate constant vs. the inverse temperature, is the correct answer.
