Worksheet: Arrhenius Plots
In this worksheet, we will practice estimating activation energies and frequency (preexponential) factors from Arrhenius plots of reaction rate.
A reaction was performed repeatedly with the same reactant concentrations but different reaction temperatures, . The initial rate was measured for each reaction. Which of the following graphs could be used to estimate the activation energy of the reaction?
- A against
- B against
- C against
- D against
- E against
The rate constant for a reaction, , was measured over a range of reaction temperatures, . The data were plotted on a graph of against . What is the activation energy for the reaction in terms of the slope of the plot ?
