Question

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 primary method used to produce most of the world's fertilizer. Suppose a chemical engineer studying a new catalyst for the Haber reaction finds that 671 liters per second of dinitrogen are consumed when the reaction is conducted at 271°C and 0.99 atm. Calculate the rate at which ammonia is being produced, and provide your answer in kilograms per second. Please round your answer to the appropriate number of significant figures.

0.19 kg/sExplanation:1) Word equation (given):•Dinitrogen gas + dihydrogen gas → gaseous ammonia. 2) Chemical equation:•N₂ (g) + 3H₂ (g) → 2NH₃ (g)3) Mole ratios:•1 mole N₂ (g) : 3 mole H₂ (g) : 2 mole NH₃ (g)4) Reaction rates: •Rate of dinitrogen consumption: r₁ = n₁ / t (moles/s)•Rate of ammonia production: r₂ = n₂ / t (moles/s)•Due to the stoichiometric ratios: r₂ = 2 × r₁5) Calculate r₁:•284 liter / s•PV = nRT ⇒ n = PV / (RT)•Divide by time, t: n/t = P (V/t) / (RT)•Substitute V/t = 284 liter/s, P = 0.75 atm, and T = 196 +273.15K = 469.15Kr₁ = n₁ / t = (0.75 atm) (284 liter/s) / [ (0.08206 atm-liter/K-mol) (469.15k) ] = 5.53 moles/s6) Calcualte r₂r₂ = 2 × r₁ = 2 × 5.53 mole/s = 11.06 mole/s7) Convert rate in mole/s to rate in kg/smass in grams = molar mass × number of molesmolar mass of NH₃ = 17.03 g/molmass = 17.03 g/mol × 11.06 /s = 188.4 g/sConvert 188.4 g/s to kg/s: 0.1884 kg/sCorrect number of significan digits: 2 (since the pressure is given with 2 significant figures. 0.19 kg/s

Explanation:N₂       + 3H₂     =     2 NH₃1 vol                         2 vol 786 liters               1572 liters 786 liters of dinitrogen will result in the production of 1572 liters of ammonia volume of ammonia V₁ = 1572 liters temperature T₁ = 222 + 273 = 495 Kpressure = .35 atm We shall find this volume at NTP volume V₂ = ?pressure = 1 atm temperature T₂ = 273 liter . mol weight of ammonia = 17 At NTP mass of 22.4 liter of ammonia will have mass of 17 gm mass of 303.44 liter of ammonia will be equal to (303.44 x 17) / 22.4 gm = 230.28 gm =.23 kg / sec . Rate of production of ammonia = .23 kg /s .

The question is incomplete, complete question is :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 348 liters per second of dinitrogen are consumed when the reaction is run at 205°C and 0.72 atm. Calculate the rate at which ammonia is being produced.The rate of production of ammonia is 217.08 grams per second.Explanation: Volume of dinitrogen used in a second = 348 LTemperature of the gas = T = 205°C = 205+273 K = 478 KPressure of the gas = P = 0.72 atmMoles of dinitrogen = nAccording to reaction, 1 mole of dinitriogen gives 2 mole of ammonia.Then 6.385 moles of dinitrogen will give:Mass of 12.769 moles of ammonia;12.769 mol 17 g/mol = 217.08 g217.08 grams of ammonia is produced per second.So, the rate of production of ammonia is 217.08 grams per second.

The rate at which ammonia is being produced is 0.41 kg/sec.Explanation: Haber reactionVolume of dinitrogen consumed in a second = 505 LTemperature at which reaction is carried out,T= 172°C = 445.15 KPressure at which reaction is carried out, P = 0.88 atmLet the moles of dinitrogen be n.Using an Ideal gas equation:According to reaction , 1 mol of ditnitrogen gas produces 2 moles of ammonia.Then 12.1597 mol of dinitrogen will produce : of ammoniaMass of 24.3194 moles of ammonia =24.3194 mol × 17 g/mol=413.43 g=0.41343 kg ≈ 0.41 kg505 L of dinitrogen are consumed in 1 second to produce 0.41 kg of ammonia in 1 second. So the rate at which ammonia is being produced is 0.41 kg/sec.
