Chemical equilibrium

Question 1

Closed system

Answer 1

• system which allows the transfer of energy
• but not matter
• (i.e. reactants and products can NOT enter or escape)

Question 2

Dynamic equilibrium

Answer 2

• continuous reaction
• closed system
• rate of the forward reaction is equal to the rate of the reverse reaction

Question 3

Heterogeneous equilibrium

Answer 3

equilibrium where chemical substances are different physical states

Question 4

Homogeneous equilibrium

Answer 4

equilibrium where all chemical substances are in the same physical state

Question 5

Le Chatelier’s principle

Answer 5

• When a system in dynamic equilibrium is
  subjected to a change
• position of the equilibrium will shift to minimise the change
