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.
