In the Haber reaction, patented by German chemist Fritz Haber in 1908, dinitrogen gas combines with dihydrogen gas to produce gaseous ammonia. This reaction is now the first step taken to make most of the world's fertilizer. Suppose a chemical engineer studying a new catalyst for the Haber reaction finds that 731. liters per second of dinitrogen are consumed when the reaction is run at 195. °C and 0.76 atm. Calculate the rate at which ammonia is being produced. Give...
