Concentration

Question 1

What happens if the concentration of reactant is increased?

Answer 1

If the concentration of a reactant is increased the equilibrium will shift in the direction of the reaction that uses the reactants, so that the reactant concentration decreases. The forward reaction is favoured.

Question 2

What happens if the concentration of the product is increased?

Answer 2

The forward reaction is also favoured if the concentration of the product is decreased, so that more product is formed.

Question 3

What happens if the concentration of reactant is decreased?

Answer 3

If the concentration of a reactant is decreased the equilibrium will shift in the direction of the reaction that produces the reactants, so that the reactant concentration increases. The reverse reaction is favoured.

Question 4

What happens if the concentration of the product is increased?

Answer 4

The reverse reaction is also favoured if the concentration of the product is increased, so that product is used.
