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

Question

Quizplus · Accepted Answer

The linear form of the Arrhenius equation is ln(k) = ln(A) - Ea/(R*T), where k is the rate constant, A is the frequency factor (also known as the pre-exponential factor), Ea is the activation energy, R is the gas constant, and T is the temperature in Kelvin. The slope of the plot of ln(k) versus 1/T gives -Ea/R, allowing calculation of the activation energy, and the intercept gives ln(A), allowing calculation of the frequency factor.
