Answer:

ΔG°  =  - 27627.1  Joules

ΔE° =  0.290 V

Explanation:

We have to apply the values in two formulas, for ΔG° and ΔE°

ΔG° = - R . T . lnK

ΔE° = 0.06 / n . log K

where T is absolute T°

R is the Ideal Constant Gases

K is Equilibrium constant.

n is the number of e⁻ gained or released during the redox

ΔG° = - R . T . lnK

ΔG° = - 8.31 J/K . 298K . ln 7x10⁴

ΔG°  = - 27627.1  Joules

This reaction is spontaneous

ΔE° = 0.06 / 1 . log 7x10⁴

n = 1

ΔE° =  0.290 V
