1. Determine the open circuit, internal entropy production rate per unit molar flow rate of CO in the carbon monoxide?oxygen fuel cell, CO +0:5(O2) → CO2, when each component in the reaction is at 25.0°C and 0.100 MPa.
2. An inventor claims to have invented a fuel cell that contains a catalyst for the ammonia reaction N2 +3H2 → 2NH3 at the standard reference state. The molar enthalpy of formation of ammonia = -19,750 Btu/lbmole and the Gibbs function of formation of ammonia = -7140 Btu/lbmole. Determine
a. The maximum theoretical reaction efficiency.
b. The maximum theoretical electrical work output of this fuel cell per lbmole of N2 consumed.
