Use the stаndаrd hаlf-cell pоtentials listed belоw tо 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
