CoCI 4 2- +6H 2 O →Co(H 2 O) 6 2+ + 4CI - . What would happen when H 2 O is added?

Position of equilibrium will shift to right (and become more pink)

Position of equilibrium will shift to left (and become more blue)

K eq will increase as H 2 O is added

Position of equilibrium will shift to left to reduce the added H 2 O

1N 2 + 3H 2 →2NH 3 When the pressure on the system is increased, the equilibrium position shifts to the right. Why?

To reduce the pressure, as the right side has fewer molecules of gas

To increase the amount of products

K eq will increase when it is shifted to the right

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

CoCI 4 2- +6H 2 O →Co(H 2 O) 6 2+ + 4CI - What will happen when CI - ions are added?

Position of equilibrium will shift to left to reduce the added CI - ions

Position of equilibrium will shift to left and become more pink

Color of system will turn to all pink

Concentration of reactants and products remain unchanged

2CrO 4 2- + 2H + → Cr 2 O 7 2- + H 2 O What will happen when H + ions are added to the system?

Equilibrium will shift to right and become more orange

Position of equilibrium will shift to left and become more yellow

Color of system will turn all yellow

Color of system will turn all orange

Heat + 1 N 2 O 4 → 2 NO 2 What will happen when the temperature is increased?

Position of equilibrium will shift to right and become more brown

Position of equilibrium will shift to left and become lighter in color

No change in position of equilibrium

Position of equilibrium will shift to right and become lighter in color

CoCI 4 2- +6H 2 O →Co(H 2 O) 6 2+ + 4CI - + Heat What will happen when the temperature is increased?

Position of equilibrium will shift to left and become more blue

Position of equilibrium will shift to right and become more pink

No change in position of equilibrium

Position of equilibrium will shift to left and become more pink

2CrO 4 2- + 2H + →Cr 2 O 7 2- + H 2 O What will happen when OH - ions are added to the system? HINT: They remove the H+ ions.

Position of equilibrium will shift to left and become more yellow

Position of equilibrium will shift to right and become more orange

Position of equilibrium will shift to right and become more yellow

OH - ions will not react, and thus no change is seen.
