Question
Chapter 10, Problem 10.20PAE
Interpretation Introduction
Interpretation: To understand the concept of a microstate and it relationship to the order or disorder of a system.
Concept Introduction: In theory microstate is an instantaneous image of the location and momentum of each atom and molecule in system.
According to the second law of
ΔStotal= ΔSsys + ΔSsurr > 0
Where,
ΔStotal= total entropy change for the process
ΔSsys = entropy change of the system
ΔSsurr = entropy change of the surrounding

Using reaction free energy to predict equilibrium composition
Consider the following equilibrium:
N2O4 (g) 2NO2 (g)
AG⁰ = 5.4 kJ
Now suppose a reaction vessel is filled with 1.68 atm of dinitrogen tetroxide (N204) at 148. °C. Answer the following questions about this system:
rise
Under these conditions, will the pressure of N2O4 tend to rise or fall?
x10
fall
Is it possible to reverse this tendency by adding NO2?
In other words, if you said the pressure of N2O4 will tend to rise, can that
be changed to a tendency to fall by adding NO2? Similarly, if you said the
pressure of N2O4 will tend to fall, can that be changed to a tendency to
rise by adding NO2?
If you said the tendency can be reversed in the second question, calculate
the minimum pressure of NO 2 needed to reverse it.

The preparations of two aqueous solutions are described in the table below. For each solution, write the chemical formulas of the major species present at
equilibrium. You can leave out water itself.
Write the chemical formulas of the species that will act as acids in the 'acids' row, the formulas of the species that will act as bases in the 'bases' row, and the
formulas of the species that will act as neither acids nor bases in the 'other' row.
You will find it useful to keep in mind that HF is a weak acid.
