Question

when you are given two half reactions and you are told to calculate net E^O, would you find the voltage for each reaction and subtract the two to get the answer?

Answer 1

If the values are not at standard state AND one is an oxidation half cell while the other is a reduction half cell, you calculate the voltage of each then ADD the two together.

Answer 2

one is oxidation and the other is reduction but they are at standard conditions though so how does that change things?

Answer 3

Eo oxidan half + Eo redn half = Eo cell

Answer 4

thank you =)
