Answer 1

Question

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.

(a)

Interpretation Introduction

Interpretation:

The structures of cis- and trans-polyacetylene are to be drawn.

Concept introduction:

The polymers are made from the polymerisation of monomer units. Polyacetylene is made from polymerization of ethyne molecule. Polyacetylene exist in two geometrical isomers (cis and trans).

(b)

Interpretation Introduction

Interpretation:

An explanation to show that cis- and trans-polyacetylene conduct electricity is to be stated.

Concept introduction:

The double bonds in the structures of cis- and trans-polyacetylene are present at alternative positions. These alternative positions of double bonds indicate that cis- and trans-polyacetylene are conjugated and thereby movement of electrons are possible.

(c)

Interpretation Introduction

Interpretation:

An explanation for the possibility to prepare anisotropic electrical conductivity (unusual behaviour) polyacetylene films is to be stated.

Concept introduction:

Anisotropic electrical conductivity of a polymer refers to the different conductivity of a polymer in different direction. Electrical conductivity, parallel to the layer of a polymer is high as compare to perpendicular to the layer of a polymer.

Using reaction free energy to predict equilibrium composition Consider the following equilibrium: N2 (g) + 3H2 (g) = 2NH3 (g) AG⁰ = -34. KJ Now suppose a reaction vessel is filled with 8.06 atm of nitrogen (N2) and 2.58 atm of ammonia (NH3) at 106. °C. Answer the following questions about this system: ? rise Under these conditions, will the pressure of N2 tend to rise or fall? ☐ x10 fall Is it possible to reverse this tendency by adding H₂? In other words, if you said the pressure of N2 will tend to rise, can that be changed to a tendency to fall by adding H₂? Similarly, if you said the pressure of N2 will tend to fall, can that be changed to a tendency to rise by adding H₂? If you said the tendency can be reversed in the second question, calculate the minimum pressure of H₂ needed to reverse it. Round your answer to 2 significant digits. yes no ☐ atm ☑ 5 00. 18 Ar
