An iron plate of 0.559 m2 surface area is to be chrome plated using a chromic acid-sulfuric acid plating bath. The anode and cathode half-equations are:

Cathode: Cr2O72-(aq) + 14 H+(aq) + 12 e-→ 2 Cr(s) + 7 H2O(l) = 0.320 V
Anode: 2 H2O(l) → O2(g) + 4 H+(aq) + 4 e- = 1.229 V

Determine the minimum energy needed to produce a plating 0.115 mm thick on the iron plate. The density of chromium is 7.19 g/cm3.
