Answer 2

The entropy change for polymerization of ethylene is negative

Explanation:

• Polymerization is the process of reacting monomers together in a chemical reaction and converting them into a macromolecule. Enthalpy and entropy are two major factors that contribute to the process of polymerization, thermodynamically.

$\Delta G = \Delta H - T\Delta S$

• Here $\Delta S$ is the change in entropy we are concerned about. This change in entropy is more or less similar in most polymerization reactions.
• This happens because the number of degrees of freedom is reducing in every polymerization reaction. Degrees of freedom depends on the different kinds of motion of the molecule.
• Therefore the entropy change $\Delta S$ in a polymerization reaction is always negative.
