Consider the following equilibrium:
N,0, (g) = 2NO, (3)
AG' = 5.4 kJ
Now suppose a reaction vessel is filled with 0.496 atm of nitrogen dioxide (NO,)
at 137. °C. Answer the following questions about this system:
O rise
Under these conditions, will the pressure of NO, tend to rise or fall?
O fall
Is it possible to reverse this tendency by adding N,O,?
In other words, if you said the pressure of NO, will tend to rise, can that
O yes
be changed to a tendency to fall by adding N,04? Similarly, if you said
O no
the pressure of NO, will tend to fall, can that be changed to a tendency to
rise by adding N,0,?
If you said the tendency can be reversed in the second question, calculate
the minimum pressure of N,0, needed to reverse it.
O atm
