Calculating the reaction rate of one Peactant from that of ano 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 394. liters per second of dinitrogen are consumed when the reaction is run at 209. °C and the dinitrogen is supplied at 0.45 atm. Calculate the rate at which ammonia is being produced. Give your answer in kilograms per second. Be sure your answer has the correct number of significant digits. X G 區 ol A 5
