IB Chemistry 2.2.13 (HL) Arrhenius factor (A) Questions
Practise identifying what the Arrhenius factor A represents, relating it to molecular orientation and reactant nature, and calculating A from graph intercepts.
How this is tested
- identify A as the factor linked to collisions with correct orientation
- distinguish that the nature of reactants influences the pre-exponential factor
- calculate A from the y-intercept of an Arrhenius plot using ln A
