QUESTION 1 The following cell notation contains two half-reactions. Pt | Fe2+(aq), Fe3+(aq) || Sn4+ (aq), Sn2+(aq) | Pt Which of the following statement/equation correctly describes the two half-reactions? anode: Pt + e → Fe3+ (aq) +Fe2+(aq); cathode: Sn4+ (aq)+Sn2+(aq)+2e->Pt -> anode: Fe2+(aq)-e→Fe3+(aq); cathode: Sn2+(aq)+2e→Sn4+ (aq) anode: Sn4+ (aq)+2e-Sn2+(aq); cathode: Fe2+(aq)-e-Fe3+ (aq); anode: Fe2+(aq)-e-Fe3+(aq); cathode: Sn 4+ (aq)+2e-Sn2+(aq) anode: Fe3+(aq)+e-Fe2+(aq); cathode: Sn2+(aq)+2e-Sn3+(aq) Based on the cell notation given in the last question, write the correct cell reaction? Fe2+(aq) + Sn4+(aq) Fe3+(aq) + Sn²+(aq) Fe2+(aq) + Fe3+(aq) Sn 4+ (aq) + Sn2+(aq) 2Fe3+(aq) + Sn2+(aq) 2Fe2+(aq) + Sn4+ (aq) Fe3+(aq) + Sn2+(aq) -> t 2Fe2+(aq) + Sn4+(aq) 2Fe3+(aq) + Sn2+(aq) Fe2+(aq) + Sn4+ (aq) Using data provided in the table of Standard Potentials (folder name: Chapter Lecture Notes), calculate standard emf of the cell described in the last question for example, 1.056 is written as 1.06. Pay attention to the sign..
