Oxidation of ammonia takes place in a continuous tubular reactor, given by:
NH3 + O2 → NO + H2O
The input stream, at 25°C, contains 100 kmol/h of NH3 and 200 kmol/h of O2. If the fractional conversion of ammonia is 100% and the products leave the reactor at 300°C, calculate the heat transferred or released to or from the reactor, Q. Note: Assume P = 1 atm.
