If a half-cell has E° = +0.80 V and the measured potential at a given condition is +0.60 V, what does this indicate about the reaction propensity under those conditions?

• A. The observed potential being lower than E° suggests the reaction is more favored under those conditions.
• B. The measured potential indicates faster kinetics dominating the process.
• C. The observed potential being lower than E° suggests the reaction is less favored under those conditions; kinetics and concentrations influence the actual potential.
• D. The reaction propensity is the same as E°, regardless of conditions.

Answer: (C)
