question 48

Multiple Choice

Calculate the standard reduction potential for the given reaction at 25 °C. AuCl₄^-(aq) + 3 e^- → Au(s) + 4 Cl^-(aq)
The thermodynamic information is as follows:
Au³⁺(aq) + 3 e^- → Au(s)
E° = +1.50 V
Au³⁺(aq) + 4 Cl^-(aq) → AuCl₄^-(aq)
K_f = 2.3 × 10²⁵

• A) -1.28 V
• B) -0.50 V
• C) +1.00 V
• D) +1.28 V
• E) +3.85 V
