Just want to make sure both of these methods work given two reduction potentials of a redox rxn.

Method 1: Rewrite the half reaction for the thing being oxidized (change the sign on the redox half rxn given) and add the values for each rxn. So you have reduction potential plus oxidation potential.

Method 2: Keep both half reaction potentials written as is (typically as reduction potential) and subtract anode from cathode.

Right?

yup, personally I find the first method to be the better one for me. Less chance for mistakes. Also remember not to ever multiply the reduction / oxidation potentials by stoichiometric coefficients

Yea the first method is my method of choice as well. It seems like Kaplan and TPR both like method 2 though.

well they can suck it
