  1. Question 1

    Q1. For a cell reaction, the Nernst equation is E = E° - 0.0592 / n * log(Q). What is 'n' for the reaction: Zn + Cu²⁺ → Zn²⁺ + Cu?

    • A) 1
    • B) 2
    • C) 3
    • D) 4

    Answer: 2

    Explanation: The number of electrons transferred (n) in the reaction is 2, as Zn → Zn²⁺ + 2e^- and Cu²⁺ + 2e^- → Cu.
