Read the wording for your board, then hide it and explain feasibility prediction in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Compare E⦵ values so that the more positive half-equation runs forwards as a reduction and the more negative one is forced backwards as an oxidation.
A reaction is predicted to be feasible when the standard cell potential is positive, corresponding to a negative standard Gibbs energy change.
