2. At 25 °C and pH 7, a solution containing compound A and its reduced form AH₂ has a standard electrode potential of -0.60 V. A solution containing B and BH2 has a standard potential of -0.16 V. If a cell were constructed with these systems as half- cells, a. Would AH2 be oxidized by B or BH2 oxidized by A under standard conditions? b. What would be the reversible emf of the cell? c. What would be the effect of pH on the equilibrium ratio [B][AH₂]/[A][BH2]?
