The catalyzed combustion of ammonia is one of the steps in the manufacture of nitric acid. The reaction involves the oxidation of NH3 (molar mass = 17 g / mol) with gaseous oxygen. They are produced mononitrogênio monoxide (nitric oxide) and water vapor. Suppose air containing 80% nitrogen and 20% oxygen by volume is used in the reaction and the speed of air consumption is 56 m³ / min, measured at STP (0 degrees Celsius and ATM), a reactor that operates a 100% yield. Under these conditions, the amount of ammonia consumed in 1 hour of reactor operation is?: "
result: 408 kg
I explain how to answer this.
