Question

Consider R2+ at standard conditions. What is the Eocell (in volts)? Final answer: two decimal places; include negative sign whenever applicable; no unit necessary. Use data given in Table 1.

2R3+(aq) + 2J-(aq) → 2R2+(aq) + J2(s)  hypothetical reaction

Table 1. Standard Reduction Potentials at 25oC of Some Hypothetical Substances

           A3+ + 3e- → A           Eo = + 1.4 V

           X2+ + 2e- → X           Eo = - 2.87 V

          R3+ + e- → R2+         Eo = + 1.61 V

           J2 + 2e- → 2J-            Eo = + 0.26 V

          L2+ + 2e- → L             Eo = - 2.36 V

          T2+ + 2e- → T             Eo = - 0.14 V
