CoCI₄^2- +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)

• K_eq will increase as H₂O is added

• Position of equilibrium will shift to left to reduce the added H₂O

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

• K_eq will increase when it is shifted to the right

• To increase the pressure, as the right side has more molecules of gas
