Question

For spontaneous polymerization, which of the following is (are) correct?

• A. $\Delta G$ is negative
• B. $\Delta H$ is negative
• C. $\Delta s$ is positive
• D. $\Delta s$ is negative

Answer 1

Answer: (A), (B), (D)

The correct options are
A $\Delta G$ is negative
B $\Delta H$ is negative
D $\Delta s$ is negative

For spontaneity, $\Delta G$ should be -ve. In polymerisation reaction lot of heat is generated, so $\Delta H$ is -ve. And the final product from monomer i.e. polymer is well defined structure (orderly manner), so $\Delta S$ is -ve.
