The Rocket Engine A rocket engine burns a stoichiometric mixture of fuel (liquid hydrogen) in oxidant (liquid oxygen). The combustion chamber is a cylindrical container (75 cm in length and 60 cm in diameter). The combustion produces 108 kg/s of exhaust gases. If the combustion is complete, find the rate of reaction for hydrogen and for oxygen. H₂ Complete combustion 6 -75 cm 60 cm 瓜 108 kg/s
