Which of the following is the strongest reducing agent?
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.)
3 Cl2(g) + 2 Fe(s) → 6 Cl⁻(aq) + 2 Fe3+(aq)
Cl2(g) + 2 e⁻ → 2 Cl⁻(aq) E° = +1.36 V
Fe3+(aq) + 3 e⁻ → Fe(s) E° = -0.04 V
Determine which of the following pairs of reactants will result in a spontaneous reaction at 25°C.
