Consider the following equilibrium:
2NOCl(g) ⇌ 2NO(g) + Cl2(g) ΔG˚= 41.kJ
Now suppose a reaction vessel is filled with 2.47 atm of nitrosyl chloride (NOCl)
and 0.960 atm of chlorine (Cl2) at 986.˚C. Answer the following questions about
this system:
Under these conditions, will the pressure of Cl2 tend to rise or
fall?
☒Rise
☐Fall
Is it possible to revese this tendency by adding NO?
In other words, if you said the pressure of Cl2 will tend to rise,
can that be changed to a tendency to fall by adding NO?
Similarly , if you said the pressure of Cl2 will tend to fall, can
that be changed to a tendency to rise by adding NO?
☒Yes
☐No
If you said the tendency can be reversed in the second
question, calculate the minimum presure of NO needed to
reverse it.
