The value for the standard emf (electromotive force) of a galvanic cel – InterviewSolution

1.	The value for the standard emf (electromotive force) of a galvanic cell described by the balanced chemical equation is 0.79 V. Determine the value of the standard half-cell potential for the I−/I2 couple.Cr2O2−7(aq)+2I−(aq)→I2(g)+Cr3+(aq)E∘Cr2O2−7/Cr3+=1.33 V
Answer» The value for the standard emf (electromotive force) of a galvanic cell described by the balanced chemical equation is $0.79 V$ . Determine the value of the standard half-cell potential for the $I^{-} / I_{2}$ couple. $C r_{2} O_{7}^{2 -} (a q) + 2 I^{-} (a q) \to I_{2} (g) + C r^{3 +} (a q)$ $E_{C r_{2} O_{7}^{2 -} / C r^{3 +}}^{\circ} = 1.33 V$
