Calculate AGⓇ for the following cell reaction: Tl(s) | Tl+ (aq) || Ni²+ (aq) | Ni(s) From AG, determine the standard potential for the half-reaction Tl+ (aq) + e → Tl(s) AG for TI+ (aq) is -32.4 kJ/mol. AG for Ni2+ (aq) is -45.60 kJ/mol. Standard Electrode (Reduction) Potentials in Aqueous Solution at 25°C Cathode (Reduction) Half-Reaction Ni²+ (aq) + 2e¯¯ ⇒ Ni(s) AG = Standard Potential, E° (V) -0.23 Standard reduction potential for the half-reaction = V
