Chapter 29, Problem 29.7QAP
Interpretation Introduction
(a)
Interpretation:
The effect of increase in the flow rate on the elution time of supercritical carbon dioxide in an SFC experiment is to be explained at constant pressure and temperature.
Concept introduction:
The time that falls in between the entry of the solute into the column and the starting of elution of the solute is termed as the elution time. There are in total three factors that affect the elution time such as flow rate, pressure and temperature.

Using reaction free energy to predict equilibrium composition
Consider the following equilibrium:
2NH3 (g) = N2 (g) +3H₂
—N2 (g) AGº = 34. kJ
Now suppose a reaction vessel is filled with 4.19 atm of ammonia (NH3) and 9.94 atm of nitrogen (N2) at 378. °C. Answer the following questions about this
system:
rise
Under these conditions, will the pressure of NH 3 tend to rise or fall?
☐ x10
fall
Х
Is it possible to reverse this tendency by adding H₂?
In other words, if you said the pressure of NH 3 will tend to rise, can that
be changed to a tendency to fall by adding H₂? Similarly, if you said the
pressure of NH3 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.
