OCR Arrhenius equation revision notes, A-level chemistry

Revision notes on the Arrhenius equation for the OCR A A-level chemistry specification on two pages.

A lot of students by the second year of A-level have forgotten how to do things like find the equation and intercept of a straight line graph, so this set of notes has a lot of recap. There’s also a lot of detailed breakdown of the log equation and how it’s a straight line graph. I explain what ln(A) is and how to calculate it.

Includes a lot of model calculations, recap of straight line graphs and explanation of the confusing units of the H432/01 2018 paper’s graph.

Update, 13/05/24: a missing 0 in the explanation of the 2018 paper’s units has been corrected, my apologies for the glitch.
