Answer #1

During the polymerization of vinyl chloride to polyvinyl chloride, one C=C bond(double bond) is broken and two C-C (single bonds) bonds are formed.

Since bond breaking requires energy and bond formation releases energy, and we know that one C=C double bond breakage requires 620KJ and one C-C single bond formation releases 340KJ energy.

Net energy of the process = 620 - 2x(340) = -60KJ

Total 60KJ energy is released per one mole of vinyl chloride when it is polymerized.

One mole of Vinyl chloride means 62.5 grams (since molecular weight of the vinyl chloride is 62.5 grams/mol).

If 62.5 grams of vinyl chloride releases 60KJ of energy when it is polymerised, then the energy released upon polymerization of one gram of vinyl chloride = (1/62.5) x 60

= 0.96KJ

(please not that one gram of vinyl chloride would produce one gram of PVC upon polymerization)
