What is the equilibrium constant (K c ) for the reaction: Cu(s) + 2Ag+(aq) → Cu2+(aq) + 2Ag(s) if the standard cell potential (Eo (cell) is 0.46 V)?

Options

  1. A0.46
  2. B3.19
  3. C1015 × 2
  4. D3.92 × 1015

Correct answer

D. 3.92 × 1015

Step-by-step solution

Eo (cell) = 0.059V ÷ 2 log K C = 0.46 or log K C = (0.46V x 2) ÷ 0.059V = 15.6 K C = 3.92 x 1015
