Molten carbonate fuel cells (MCFC) are newly developed fuel cells that commonly use molten lithium and potassium carbonates as electrolytes. The half-reactions in the cell are shown below:
Anode:H₂(g) + CO₃^2–(l) → H₂O(l) +CO₂(g) + 2 e^–
Cathode: 1/2 O₂(g) + CO₂(g) + 2 e^– → CO₃^2–(l)
Using the thermodynamic values below, determine the cell potential (E°) and the equilibrium constant (K) for the overall reaction at 25°C. Identify whether the values of E° and K will increase, decrease or remain unchanged as the temperature decreases.
