4.78. Ethylene oxide is produced by the catalytic oxidation of ethylene: $2{\mathrm{C}}_2{\mathrm{H}}_4+{\mathrm{O}}_2?2{\mathrm{C}}_2{\mathrm{H}}_4\mathrm{O}$ An undesired competing reaction is the combustion of ethylene: ${\mathrm{C}}_2{\mathrm{H}}_4+3{\mathrm{O}}_2?2{\mathrm{CO}}_2+2{\mathrm{H}}_2\mathrm{O}$ fresh feed, (ii) the production rate of ethylene oxide, and (iii) the overall conversion of ethylene. Do no calculations. b. Calculate the quantities specified in Part (a), either manually or with an equation-solving program. c. Calculate the molar flow rates of ethylene and oxygen in the fresh feed needed to produce 1 ton per hour of ethylene oxide.
