Question

For the reduction of Cu2+by Zn, ∆G◦=−212 kJ/mol and E◦= +1.10 V. If the
coefficients in the chemical equation for this reaction are multiplied by 2, ∆G◦=−424 kJ/mol. This means E◦= +2.20 V.
True or false?

Answer 1

false.
E for the rxn is 1.10v and that is true with a little Zn and a little Cu^2+ or a big log of each.

Answer 2

false
