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

A 2 (g) + 2B 2 (g) <--> 2AB 2 (g) ΔH = + kJ What stress is occurring at time 6min?

increase in concentration of AB 2

decrease in concentration of AB 2

Which of the following could be the equilibrium reaction for the graph shown?

It cannot be determined using this graph

What states of matter are included when calculating K eq ?

Solids, Liquids, Aqueous solutions and Gases

There are more products than reactants when the reaction reached equilibrium.

There are more reactant than products when the reaction reached equilibrium.

The amount of reactants is equal to the amount of products.

Why is equilibrium called a dynamic state?

The reactions at equilibrium continue to take place once equilibrium is established.

Chemists try to convert as much reactants as possible into products.

The products of a forward reaction are favored, so equilibrium lies to the right.

All chemical reactions are considered to be reversible under suitable conditions.

What is the equilibrium expression for: Fe 3 O 4 ( s ) + 4H 2 (g) <=> 3Fe( s ) + 4H 2 O(g) K eq =

K eq = [Fe] 3 [H 2 O] 4 / [Fe 3 O 4 ] [H 2 ] 4

K eq = [Fe 3 O 4 ] [H 2 ] 4 / [Fe] 3 [H 2 O] 4

K eq = [Fe] [H 2 O] / [Fe 3 O 4 ] [H 2 ]
