Z n | Z n 2 + ( C 1 ) | | Z n 2 + ( C 2 ) | Z n . For this cell Δ G is negative if

Options

  1. AC 1 = C 2
  2. BC 1 > C 2
  3. CC 2 > C 1
  4. DNone of these

Correct answer

C. C 2 > C 1

Step-by-step solution

A n o d e: Z n → Z n + 2 C 1 C a t h o d e: Z n + 2 C 2 → Z n K c = Z n + 2 A Z n + 2 C = C 1 C 2 E = E o - 0.0591 2 log ⁡ k c ∆ G = - n F E E = E ° - 0.0591 2 l o g C 1 C 2 = 0.0591 2 l o g C 2 C 1 to make Δ G = - v e Δ E = + v e hence, C 2 > C 1
