C5.3 Equilibria

Question 1

What is a reversible reaction?

Answer 1

A reaction where the products can react to for the original reactants. The symbol for this type of reaction is a double arrow.

Question 2

What does ‘hydrated’ mean

Answer 2

Hydrated means that the molecule is surrounded by water molecules. For example:

CuSO4.5H2O means that each copper iron is surrounded by 5 waters

Question 3

What does anhydrous mean?

Answer 3

Without water

Question 4

What does Le Chatelier’s principle state?

Answer 4

If dynamic equilibrium is disturbed by changing the conditions, the position of the equilibrium moves to counteract the change. In other words, changing the temperature of a reaction will be cancelled

Question 5

What is equilibrium?

Answer 5

When the rates of forward reaction and backward reaction become equal

Question 6

What is dynamic equilibrium?

Answer 6

When the forward and backward reactions still happen while the rates of forward and backward reaction are equal

Question 7

When does equilibrium position move?

Answer 7

The equilibrium position give you an idea of the ratios between the reactants and products
