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)
