Question 24 of 60

24) Given the reduction potentials for the following half-reactions,

Br₂ (l) + 2e^– -> 2 Br^–(aq) E^o_red= + 1.07 V

Au³⁺ (aq) + 3 e^– -> Au (s) E^o_red= + 1.55 V

What is the electrochemical potential for the following chemical reaction?

2 Au³⁺ (aq) + 6 Br^–(aq) -> 3 Br₂ + 2 Au (s) E^ocell = ?

E^o = – 0.48 V
E^o = – 0.11 V
E^o = + 0.11 V
E^o = + 0.48 V
