Trichloroethylene, a widely used degreasing solvent for machine parts, is produced in a two step reaction sequence. Ethylene is first chlorinated to form tetrachloroethane, which is dehydrochlorinated to form trichloroethylene. The standard heat of formation of liquid trichloroethylene is ?276.2 kJ/mol. (a) Use the given data and tabulated data for ethylene and HCl to calculate for tetrachloroethane and of the second reaction. (b) Calculate the standard heat of the reaction (c) If 300 mol/h of trichlorethylene is produced at 25 C and 1 atm, how much heat is evolved or absorbed in the process?
