63. Ethylene, C2H4, used to make polyethylene plastics, can be made from ethane, C2H6, one of the components of natural gas. The heat of reaction for the decomposition of ethane gas into ethylene gas and hydrogen gas is 136.94 kJ per mole of C2H4 formed, so it is endothermic. The reaction is run at high temperature, in part because at 800-900 °C, the equilibrium constant for the reaction is much higher, indicating that a higher percentage of products forms at...

Ethylene oxide is produced by the catalytic oxidation of ethylene: C2H4 (g) + 1/2 O2 (g) --> C2H4O (g) An undesired competing reaction is the combustion of ethylene to CO2. The feed to a reactor contains 2 mol C2H4/mol O2. The conversion and yield in the reactor are respectively 25% and 0.70 mol C2H4O produced/mol C2H4 consumed. A multiple-unit process separates the reactor outlet stream components: C2H4 and O2 are recycled to the reactor, C2H4O is sold, and CO2 and...

Ethylene, C2H4 is a reactive gaseous hydrocarbon. Two students were set loose in a lab and tried to react ethylene with hydrogen gas and hydrochloric acid. Due to the humidity that day there was also water in the reaction. When the students analyzed their products, they found three products came from the reaction. They were able to make ethane (C2H6), 1-chloro-ethane (C2H5Cl)and ethyl alcohol (C2H5OH). In these products, one is a liquid at room temperature and two are gases. Use...

Ethylene(C2h4) enters reactors at a rate of 1 kmole per minutes at a temperature of ( 25 C )and 1 atm of pressure. A stoichiometric amount of oxygen (O2) also enters the reactor at the same temperature and pressure. Complete combustion occurs within the reactor. the combustion products pass through a heat exchanger where some heat is transfer from the gases. the gases then exit the heat exchange with a temperature of 800 K and the pressure of 1 atm....
