please answer all the questions
thank you
Nitric oxide (NO) is a gas that decomposes in air, therefore it is usually made when it is needed immediately. The most common use of nitric oxide is as fertilizer. In order to produce nitric oxide, 25 kmol/h of ammonia (NH3) and a stream of oxygen (02), both at 25°C and 1 atm, are fed into a continuous reactor packed with catalyst in which ammonia is completely consumed. The product gas emerges at...
