For the cell reaction at 25°C Cu²⁺(aq) + Zn(s) → Cu(s) + Zn²⁺(aq), E°cell = +1.100 V. What is the equilibrium constant for this reaction?

Question

Quizplus · Accepted Answer

The equilibrium constant (K) can be calculated using the Nernst equation: E°cell = (RT/nF)lnK. At 25°C, this simplifies to E°cell = (0.0592/n)logK. For this reaction, n = 2. Solving for K gives K = 10^(nE°cell/0.0592) = 10^(2*1.100/0.0592) ≈ 2 × 10^37.
