For the given cell reaction: A converts to A⁺ by losing an electron, and B⁺ gains an electron to form B. The overall reaction is A + B⁺ → A⁺ + B. Which of the following is correct?

1. E° = 0.0591/n log₁₀ K
2. log₁₀ K = 2 × 0.295 / 0.0591
3. K = 1 × 10¹⁰
4. n = 2, E° = 0.295

Correct answer: n = 2, E° = 0.295

Solution

The given reaction involves the transfer of 1 electron (n = 1) for each half-reaction. The standard cell potential (E°) is given as 0.295 V, which matches the data provided in option D.
