7) Chemical equilibrium

Question 1

What are the characteristics of a dynamic equilibrium

Answer 1

• The rate of the forward reaction is equal to the rate of the backwards reaction
• The concentration of reactants and products do not change/ remains constant
• It has to be a closed system

Question 2

What does Le Chatelier’s principle states

Answer 2

When any of the conditions affecting the position of a dynamic equilibrium will shift to minimise that change

Question 3

State the effect on the position of the equilibrium and the composition of the reaction mixture when increasing the reactants concentration

Answer 3

• Concentration of reactants increases
• This favours the forward reaction to minimise the change
• The equilibrium will shift to the right
• Increase in product concentration and a decrease in reactants concentration
