Use the standard half-cell potentials listed below to calculate the standard cell potential for the following reaction occurring in an electrochemical cell at 25°c. (the equation is balanced.) pb(s) + br2(l) → pb2+(aq) + 2br(aq) pb2+(aq) + 2 e → pb(s) e° = -0.13 v br2(l) + 2 e → 2 br(aq) e° = +1.07 v
