CO + H20g) → CO29) + H2G)
(e) After the carbon dioxide gas is removed by dissolving it in water, the hydrogen
reacts with nitrogen in the air to form ammonia.
N2G) + 3 H2g) → 2 NH3G)
5. Nitric acid, required in the production of nitrate fertilizers, is produced from
ammonia by the Ostwald process. Use standard enthalpies of formation to calcu-
late the enthalpy changes in each of the following systems.
