Vinyl chloride can be synthesized by reaction of acetylene with hydrochloric acid over a mercuric chloride catalyst at 500 K and 5.0 atm total pressure. An undesirable side reaction is the subsequent reaction of vinyl chloride with HCI. These reactions are illustrated below. HC=CH + HCi € H,C=CHCI (1) acetylene vinyl chloride H,C=CHCI + HCI O H;C-CHCI, (2) 1,2 dichloroethane The equilibrium constants at 500 K are 6.6 X 10° and 0.88 for reaction i and 2, respectively. Assume ideal behavior. (a) Find the equilibrium composition at 5.0 atm and 500 K for the case when acetylene and HCI are present initially as an equimolar mixture. What is the equilibrium conversion of acetylene? (b) Redo part (a) with a large excess of inert gas. Assume the inert gas constitutes 90 vol. % of the initial gas mixture.
