Calculate Eo

(So im assuming that CL does not change so i discluded it now im stuck with a reaction with a negative E which im pretty sure is wrong)

DrBob222 · Answer

If you had shown your work I could find the error. You're right, the Cl doesn't change oxidation state; however, it enters the reaction (formation PbCl2) so it should be included in the equation.And I assume you meant to say USE Eo to calculate Ereaction.
