Answer
(a) The equilibrium shifts to right.
(b) The equilibrium will remain unchanged.
(c) The equilibrium shifts to left.
(d) The equilibrium shifts to right.
(e) The equilibrium shifts to right.
Work Step by Step
Decreasing the volume of a system will cause a shift in the equilibrium on the direction that has the least amount of moles of gases.
If both sides have the same amount, the equilibrium will not be affected.
