Ammonia is produced industrially by reacting N2 with H₂ at elevated pressure and temperature in the presence of a catalyst: N₂(g) + H₂(g) → NH3(g) (unbalanced) In actual practice, this reaction gives a yield of only 13%, taking this into account what mass of ammonia would be produced from a 1:1 mole ratio mixture in a reactor that has a volume of 3.91 x 103 L, under a total pressure of 116 bar at T = 632 °C? Actual amount = g مه

[References] Ethene is converted to ethane by the reaction Catalyst C2H4 (9) + H2 (9) C2H6 (g) ot C2H4 flows into a catalytic reactor at 28.7 atm and 300.°C with a flow rate of 1150. L/min. Hydrogen at 28.7 atm and 300.°C flows into the reactor at a flow rate of 1450. L/min. If 14.8 kg C2 H6 is collected per minute, what is the percent yield of the reaction? pt Percent yield pt
