engineering chemistry MCQ #2774

  1. Question 1

    Q1. The standard electrode potential for the reaction Ag⁺ + e⁻ → Ag is 0.80 V. The potential for the cell Ag / Ag⁺ (0.1 M) // Ag⁺ (1 M) / Ag is

    • A) 0.0591 V
    • B) -0.0591 V
    • C) 0.80 V
    • D) 0.0 V

    Answer: -0.0591 V

    Explanation: Using Nernst equation, E_cell = E⁰ - 0.0591 / n log([Ag⁺]ₐₙₒₜₑ / [Ag⁺]ₗₐₜₕₒₜₑ), where n = 1.
