In the Haber process, nitrogen
N2 and hydrogen H2 gases combine to give ammonia
gas NH3 as the only product. If 5.55 L of nitrogen gas
completely reacts, calculate the volume of ammonia that is produced. Assume all
volumes of gas are measured under constant conditions of 500 oC and 300 atm
pressure. How many liters of hydrogen are required to complete react the 5.55L
of nitrogen?
