Identifying the major species in weak acid or weak base equilibria
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.

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.
