Topic 17: Equilibrium (HL)

Question 1

ICE

Answer 1

I: Initial concentration of the reactants [products]=0

C: change in concentration

E: Equilibrium concentration is the concentration of reactants and products when equilibrium is established

E = I +/- C

Question 2

Gibss free energy change when Kc = 1

Answer 2

∆G= 0

at equilibrium

Question 3

Gibss free energy change when Kc > 1

Answer 3

∆G < 0

products are favoured

Question 4

Gibss free energy change when Kc < 1

Answer 4

∆G > 0

reactants are favoured
