What is the half-reaction occurring at the cathode in an electrochemical cell with overall reaction of: 3 Mno"(aq) + 24 H* (aq) + 5 Fe(s) ---> 3 Mn2+ (aq) + 5 Fe3+ (aq) + 12 H2O(1) Select one: O a. Fe(s) ---> Fe3+ (aq) + 3 e Ob. Fe(s) ---> Fe2+ (aq) + 2 e O c. 2 MnO,- (aq) + 12 H+ (aq) + 6 e ---> 2 Mn2+ (aq) + 3 H2O(1) Od. Mno." (aq) + 8H+ (aq) + 5 e ---> Mn2+ (aq) + 4H2O() O e, Fe2+ (aq) ---> Fe3+ (aq) + e
If a redox reaction occured with the 2 redox couples provided below, which species would be the reducing agent? H(aq) + HCIO (aq) + 2e → H2O(l) + CF(aq) E° = 1.49 V 8H(aq) + MnO4 (aq) + 5e + 4H2O(l) + Mn2+ (aq) E° = 1.51 V a. Cl(aq) Ob. HCIO(ag) Oc. H2000) Od. Mn2+ (aq) Oe. Mno, (aq)
