For the cell $\text{Fe}(s) \mid \text{Fe}^{2+}(aq) \parallel \text{Cu}^{2+}(aq) \mid \text{Cu}(s)$ with $E^\circ = 0.78\ \text{V}$ , which Nernst equation is correct at $298\ \text{K}$ ?

← All Quizzes

← A reaction has a large positive E° and a very large K, yet a mixture of the reactants shows no change for years. What is the most likely reason?The cell Fe(s) mid Fe²⁺(aq) ∥ Cu²⁺(aq) mid Cu(s) has E° = 0.78 V and n = 2 at 298 K. At one moment its emf is 0.85 V. What is the reaction quotient Q at that moment? →
