Topic 7.1 - Equilibrium

Question 1

K꜀

Answer 1

K꜀ > 1 : products are favoured
K꜀ < 1 : reactants are favoured

Only temperature affects the K꜀ value and if increasing temperature causes the products to be favoured, K꜀ increases (and vice versa)

Question 2

Equilibrium position in changing pressure, concentration, temperature, and/or the use of a catalyst

Answer 2

More pressure - Moves to the side with fewer gas moles

More reactant concentration - There is more reactant to react so it shifts to the opposite side

Higher temperature - Moves to the more endothermic side

Catalyst - does not impact position

Question 3

Reaction quotient

Answer 3

Tells you how far the reaction needs to go until equilibrium

Q > K꜀ = products favoured
Q < K꜀ = reactants favoured
Q = K꜀ = equilibrium
