Polyvinyl chloride (PVC) is made by addition polymerization of vinyl chloride (VCM C2H3Cl). Vynyl chloride is synthesized from ethylene(C2H4 in a two step process involving the following equilibria
C2H4(g) + Cl2(g)=C2H4Cl2(g) eq 1
C2H4Cl2(g)=C2H3Cl(g)+HCL(g)
use the average bond enthalpies to estimate the ethalpy changes for the two equilibria.How would the yeild of Vinyl chloride in Eq 2 vary with temp and volume?
