Consider the following equilibrium:
N2 (g) + 3H, (g)=2NH3 (g)
AG" = - 34. kJ
Now suppose a reaction vessel is filled with 2.80 atm of nitrogen (N,) and 2.59 atm of ammonia (NH,) at 235. °C. Answer the following questions about this
system:
rise
Under these conditions, will the pressure of NH, tend to rise or fall?
fall
Is it possible to reverse this tendency by adding H,?
In other words, if you said the pressure of NH, will tend to rise, can that
yes
be changed to a tendency to fall by adding H,? Similarly, if you said the
O no
pressure of NH, will tend to fall, can that be changed to a tendency to
rise by adding H,?
If you said the tendency can be reversed in the second question, calculate
the minimum pressure of H, needed to reverse it.
