A balanced equation that represents an overallcell reaction is shown. Choose the cell notation which correspondsto the electrochemical cell that is described by thisequation.

2Br-(aq) + S2O82-(aq) →Br2(l) + 2SO42-(aq)

Pt(s) lS2O82-(aq),SO42-(aq) ll Br-(aq) lBr2(l) l Pt(s)
Pt(s) l Br-(aq) l Br2(l) llS2O82-(aq),SO42-(aq) l Pt(s)
Pt(s) l Br-(aq) l Br2(l) llS2O82-(aq) lSO42-(aq) l Pt(s)
Pt(s) l Br-(aq) l Br2(l) llSO42-(aq),S2O82-(aq) l Pt(s)

St. Red. Pot. (V)
Br2/Br- +1.07
S2O82-/SO42- +2.01
