Dynamic equilibrium problem?
The equilibrium MOVES to the left as written.........
If pressure is increased, the equilibrium should move to the side that RELIEVES pressure; and thus the equilibrium should move to the LEFT as written, inasmuch as the LHS exerts LESS pressure. It moves in this direction so as to maintain the equilibrium and resist the external change.
We can look at this another way, if we can increase pressure such that
Anyway, please report what your teacher says...........
