Worksheet: Arrhenius Plots

In this worksheet, we will practice estimating activation energies and frequency (preexponential) factors from Arrhenius plots of reaction rate.

Q1:

A reaction was performed repeatedly with the same reactant concentrations but different reaction temperatures, 𝑇 . The initial rate 𝑅 was measured for each reaction. Which of the following graphs could be used to estimate the activation energy of the reaction?

  • A l n 𝑅 against l n 𝑇
  • B 𝑅 against 1 𝑇
  • C 1 𝑅 against 𝑇
  • D l n 𝑅 against 1 𝑇
  • E 1 𝑅 against l n 𝑇
