Lesson Worksheet: The Arrhenius Equation Chemistry • 10th Grade

In this worksheet, we will practice using the Arrhenius equation to calculate reaction activation energies and frequency (preexponential) factors.


The rate constant for a reaction, 𝑘, was measured over a range of reaction temperatures, 𝑇. The data were plotted on a graph of ln𝑘 against 1𝑇. What is the frequency (preexponential) factor for the reaction in terms of the gradient of the plot 𝑚 and the 𝑦-intercept 𝑐?

  • Bln(𝑚)
  • Cln(𝑐)
