Question

A mixture of oxygen (O2) and ammonia (NH3) in the gas state are fed to a reactor. The molar flow of oxygen is 200 mol/s and 100 mol/s of ammonia. Ammonia conversion is 100%. The chemical reaction that occurs is:

NH3(g)+1.25 O2 (g) ------- NO (g) + 1.5 H2O(v)

Calculate the heat (kJ/h) to or from the reactor to maintain the temperature in the reactor at 300°C.

Data: (CP)O2 (g) = 29.1 + 0.01158*T – 0.6076x10-5 T2
           (CP)NO (g) = 29.5 + 0.008188*T – 0.2925x10-5 T2
           (CP)H2O (v) = 33.46 + 0.00688*T – 0.2925x10-5 T2
(CP) (J/mol°C) T(°C)

Take as references: NH3 (g), O2(g), H2O(v), NO(g) at 25°C
