SUMMARY
This discussion focuses on calculating the reaction heat in an ammonia converter, specifically requiring the specific heats of nitrogen (N2), ammonia (NH3), argon (Ar), and methane (CH4) at 500°C and 200 bar. The NIST website was referenced for specific heat values, although it does not provide data for ammonia at the specified pressure. The specific heat values obtained are: Nitrogen (Cv: 0.1977, Cp: 0.2738), Ammonia (Cv: 0.6080, Cp: 0.7906), Argon (Cv: 0.07550, Cp: 0.1314), and Methane (Cv: 0.8018, Cp: 0.9490).
