What equations/ formulas are provided in the exam and which are you expected to learn?
For instance kc you need to learn and arrhenius is given

If anyone knows please share as it will be useful for others too

Hi this depends on your exam board
Search up a data sheet for your exam
e.g one for ocr = https://filestore.aqa.org.uk/resourc...A-7405-SDB.PDF
this is what you get in the exam 100%

For AQA (to learn):

1. All mol equations; solids and solutions, density equation
2. Avogadro's.
3. Ideal gas equation
4. % yield and atom economy
5. Concentrations of solutions, concentrations of a new diluted solution
6. Heat energy change equation (Calorimetry) and molar enthalpy change equation
7. Hess' Law equations (formation and combustion)
8. Kc and Kp
9. Gibbs free energy change
10. Calculating entropy change equation
11. EMF equation
12. pH equations
13. Ka and pKa equations
14. % uncertainty

That's all of the top of my head, may be a few more

Arrhenius is given, but you should know how to calculate Ea and A values from the graph (A= antilog of lnA).

15. Atom economy
16. Calculating rates from a graph
