4. Ethylene oxide (C2H4O) is produced by the reaction of ethylene (C2H4) with oxygen: 2C2H4+ O22C2H4O The feed to the reactor contains 5 mol/h of ethylene, 3 mol/h of oxygen, and 2 mol/h of ethylene oxide. Set up the compound balances in general, and then use these to solve the cases suggested as follows: a. Suppose the amount of C2H4 coming out of the reactor is 5 mol. How much reaction has occurred? b. How much reaction has occurred if the amount of C2H4-6 mol/h? c. How much reaction has occurred if the amount of C2H4=0? d. Which component is the limiting reagent? e. What is the theoretical yield? f. What is the fractional conversion if the amount of C2H4=2?
