When polymers are recycled, the ends of the long chain polymer molecules tend to break off, and this process eventually results in a degradation of physical properties, rendering the cycled polymer unusable. Why the breaking off the end of the polymer molecules is favorable from the stand point of the entropy of the system is needs to be explained. Concept introduction: Entropy is explained as degree of randomness in a system. If there are more number of molecules more will be the entropy. In polymerization , monomers combined to form polymer, thus, molecules are in more ordered form and entropy of system decreases. Opposite to this, if polymers are recycled, due to breaking of long chains of polymer, molecules are no more in ordered form. Hence, entropy increases.

Solution Summary: The author explains that when polymers are recycled, the ends of the long chain polymer molecules tend to break off, and this process eventually results in a degradation of physical properties.
Definition Definition Chemical process in which one or more monomers combine to produce a very large chain-like molecule called a polymer. The functional groups present on the monomers and their steric effects are responsible for polymerization through a sequence of reactions that vary in complexity. There exists a stable covalent chemical bond between monomers that sets apart polymerization from other processes.

Interpretation Introduction
Interpretation:
When polymers are recycled, the ends of the long chain polymer molecules tend to break off, and this process eventually results in a degradation of physical properties, rendering the cycled polymer unusable. Why the breaking off the end of the polymer molecules is favorable from the stand point of the entropy of the system is needs to be explained.

need help please and thanks dont understand a-b
Learning Goal:
As discussed during the lecture, the enzyme HIV-1 reverse transcriptae (HIV-RT) plays a significant role for the HIV virus and is an important drug target. Assume a concentration [E] of 2.00 µM (i.e. 2.00 x 10-6 mol/l) for HIV-RT. Two potential drug molecules, D1 and D2, were identified, which form stable complexes with the HIV-RT.
The dissociation constant of the complex ED1 formed by HIV-RT and the drug D1 is 1.00 nM (i.e. 1.00 x 10-9). The dissociation constant of the complex ED2 formed by HIV-RT and the drug D2 is 100 nM (i.e. 1.00 x 10-7).
Part A - Difference in binding free eenergies
Compute the difference in binding free energy (at a physiological temperature T=310 K) for the complexes. Provide the difference as a positive numerical expression with three significant figures in kJ/mol.
The margin of error is 2%.
Part B - Compare difference in free energy to the thermal energy
Divide the…
