Answer:

92.6 kJ.

Explanation:

∵ ΔG°rxn = - nFE°cell,

Where, ΔG°rxn is the standard free energy change (J).

n is the no. of electrons in the reaction (n =2).

F is Faraday constant (C/mol) (F = 96500 C/mol).

E°cell is the standard cell potential (E°cell = - 0.48 V).

∴ ΔG°rxn = - nFE°cell = - (2)(96500 C/mol)(- 0.48 V) = 92640 J = 92.64 kJ.
