For an electrochemical cell, Pt|UO2+ (0.015M), U4+ (0.2 M), H+ (0.03M) || Fe2+ (0.01M), Fe3+ (0.02M) Pt The half cell reactions are: Fe3+ + e 5 Fe2+ E = 0.771 V UO22+ + 4H+ +2e 5U4+ + 2 H20 E = 0.334 V Write the overall reaction, calculate Ecell and determine if the cell is galvanic or not (must show detailed calculation steps)
