1.6 Equilibria

Question 1

State the key features of dynamic equilibrium

Answer 1

Rate of the forward reaction equals the rate of the reverse reaction
Concentrations of reactants and products remain constant

Question 2

State Le Chatelier’s principle

Answer 2

If a system in equilibrium is subjected to a change, the position of equilibrium will moce in the direction which opposes that change

Question 3

What happens when there is an increase in total pressure?

Answer 3

Equilibrium shifts to the side with fewer moles of gas

Question 4

What happens when there is an increase in temperature?

Answer 4

Equilibrium will move in the direction of the endothermic reaction

Question 5

What happens when there is an increase in the concentration of reactants?

Answer 5

Equilibrium shifts right

Question 6

State the equation for Kc

Answer 6

Kc = Conc of produts / Conc of reactants

Question 7

What happens to Kc when temperature change shifts equilibrium right?

Answer 7

Kc increases
