For the specific electrochemical cell , what is the primary thermodynamic driving force and effect o — Electrochemistry Chemistry Question

💡 Solution & Explanation

This specific setup defines an "Electrode Gas Concentration Cell." The electrolyte concentration ($H^+$) is uniform throughout, but the pressures of the reactant gases differ ($p_1 = 1\text{ atm}$ at the anode, $p_2 = 2\text{ atm}$ at the cathode). The cell potential is determined by the Nernst equation $E = -\frac{RT}{2F} \ln \frac{p_{anode}}{p_{cathode}}$. Thus, the pressure differential uniquely generates the non-zero EMF.
