Ethane is chlorinated in a continuous reactor: C2H6 +Cl2 → C2H5Cl + HCl Some of the product monochloroethane is further chlorinated in an undesired side reaction: C2H5Cl +Cl2 → C2H4Cl2 + HCl

a. Take a basis of 100 mol of C2H5Cl produced. Assume that the feed contains only ethane and chlorine and that all of the chlorine is consumed. How many degrees of freedom remain (use atomic balances)?

b. The reactor is designed to yield a 19% conversion of ethane and a selectivity of 8 mol C2H5Cl / mol C2H4Cl2 with a negligible amount of chlorine in the product gas. Calculate the feed ratio (mol Cl2/mol C2H6).

Calculate the fractional yield (mol C2H5Cl produced / mol Cl2 consumed)

I did part a i am just confused about part b

Ethane (C2H6) is combusted in 18.1% excess oxygen (O2) in an adiabatic reactor. The feed of ethane enters the reactor at 25.8 mol/hr and 93.7°C. The stream exiting the reactor contains ethane, oxygen, carbon dioxide (CO2), carbon monoxide (CO) and water (H2O), so ethane reacts by both complete and partial combustion reactions. The conversion of ethane is 15.8% and the conversion of oxygen is 12.3%. Assume that pressure effects are negligible. (a) Draw and label a process flow diagram. Number...
