Open questionXL-PNAT2 marksNeeds review
Given the standard reduction potentials (E⊖) for the half-cell reactions below, the standard Gibbs free energy of the dissolution of silver chloride in water, at 298 K, is __________ J mol⁻¹ (rounded off to nearest integer).
(Given: Faraday constant, F = 96500 C mol⁻¹; J = C × V)
AgCl(s) + e⁻ → Ag(s) + Cl⁻(aq) ; E⊖ = 0.22 V at 298 K
Ag⁺(aq) + e⁻ → Ag(s) ; E⊖ = 0.80 V at 298 K
