Arrhenius Equation A variable

Postby EthanPham_1G » Wed Mar 11, 2020 11:37 am

Will we be given what the value for A is for the Arrhenius equation? I don't know how else you could solve for k without knowing it.

You can solve for k using this version of the Arrhenius equation: . To calculate k you need another k value for a different temperature and then you can subtract from and the lnA term will cancel.

Since A has to be solved for experimentally, we should be given it if it is needed in the equation. I think we will mostly be using the Arrhenius equation to solve for different values of k
