Edexcel IAL Chemistry A2 11.10 Arrhenius activation energy
Convert temperature to kelvin, calculate the required reciprocal or logarithmic terms, plot the stated linear form and use the signed gradient with R before converting to kJ mol⁻¹.
How this is tested
- Transform temperature and rate data into the variables specified by the Arrhenius form.
- Plot a labelled best-fit Arrhenius graph and calculate its signed gradient with units.
- Use gradient = −Eₐ/R to calculate positive activation energy in kJ mol⁻¹.
