CoCI42- +6H2O →Co(H2O)62+ + 4CI-.
What would happen when H2O is added?
Position of equilibrium will shift to left (and become more blue)
Position of equilibrium will shift to right (and become more pink)
Keq will increase as H2O is added
Position of equilibrium will shift to left to reduce the added H2O
CoCI42- +6H2O →Co(H2O)62+ + 4CI-.
What would happen when H2O is added?
Position of equilibrium will shift to left (and become more blue)
Position of equilibrium will shift to right (and become more pink)

1N2 + 3H2 →2NH3
When the pressure on the system is increased, the equilibrium position shifts to the right. Why?
To increase the amount of products
To reduce the pressure, as the right side has fewer molecules of gas
Keq will increase when it is shifted to the right
To increase the pressure, as the right side has more molecules of gas
