What is the formula for the Nernst equation in the cell reaction Ni(s) + 2Ag+(aq) → Ni2+(aq) + 2Ag(s)?

Options

  1. AE (cell) = Eo (cell) - RT/2F ln [Ni2+] / [Ag+]2
  2. BE (cell) = Eo (cell) - RT/2F ln [Ag+] / [Ni2+]2
  3. CE (cell) = Eo (cell) - RT/2F ln [Ni2+] / [Ag+]
  4. DE (cell) = Eo (cell) - RT/2F ln [Ag+] / [Ni2+]

Correct answer

A. E (cell) = Eo (cell) - RT/2F ln [Ni2+] / [Ag+]2

Step-by-step solution

The formula for the Nernst equation in the cell reactionNi(s) + 2Ag+(aq) → Ni2+(aq) + 2Ag(s) is E (cell) = Eo (cell) - RT/2F ln [Ni2+] / [Ag+]2.
