(a)

Interpretation:
The short segment of polymer obtained from the given monomer has to be drawn and also have to indicate whether it is a chain growth or step growth polymer.
Answer to Problem 24P
The short segment of given monomer is shown below and the monomer undergoes chain growth polymerization.
Explanation of Solution
Given the monomer is
The short segment of polymer obtained from this monomer is given below.
The polymer formed is a Chain growth polymer because monomer addition occurs at the end of the chain.

Answer to Problem 24P
The short segment of given monomer is shown below and the monomer undergoes step growth polymerization.
Explanation of Solution
Given the monomer is
The short segment of polymer obtained from this monomer is given below.
The polymer formed is a Step growth polymer because monomer addition occurs not at the end of the chain and these polymers are formed by combining monomers by removing small molecules of water or alcohol.

The short segment of polymer obtained from this monomer is given below.
The polymer formed is a step growth polymer because monomer addition occurs not at the end of the chain and these polymers are formed by combining monomers by removing small molecules of water or alcohol.
(e)

Interpretation:
The short segment of polymer obtained from the given monomer has to be drawn and also have to indicate whether it is a chain growth or step growth polymer.
Answer to Problem 24P
The short segment of given monomer is shown below and the monomer undergoes step growth polymerization.
Explanation of Solution
Polymers are formed from linking small units called monomers and they are classified into Chain growth polymers and Step growth polymers.
Given the monomer is
The short segment of polymer obtained from this monomer is given below.
The polymer formed is a Step growth polymer because monomer addition occurs not at the end of the chain and these polymers are formed by combining monomers by removing small molecules of water or alcohol.

Consider a two-state system in which the low energy level is 300 J mol 1 and the higher energy level is 800 J mol 1, and the temperature is 300 K. Find the population of each level. Hint: Pay attention to your units. A. What is the partition function for this system? B. What are the populations of each level? Now instead, consider a system with energy levels of 0 J mol C. Now what is the partition function? D. And what are the populations of the two levels? E. Finally, repeat the second calculation at 500 K. and 500 J mol 1 at 300 K. F. What do you notice about the populations as you increase the temperature? At what temperature would you expect the states to have equal populations?arrow_forward

We will derive the forms of the molecular partition functions for atoms and molecules shortly in class, but the partition function that describes the translational and rotational motion of a homonuclear diatomic molecule is given by Itrans (V,T) = = 2πmkBT h² V grot (T) 4π²IKBT h² Where h is Planck's constant and I is molecular moment of inertia. The overall partition function is qmolec Qtrans qrot.
