Question 0

• homogeneous equilibrium

Answer 0

An equilibrium in which all the species making up the reactants and products are in the same physical state

Question 1

• dynamic equilibrium

Answer 1

Exists in a closed system when the rates of the forwards and reverse reactions are equal

Question 2

• when the forward reaction is exothermic what happens to Kc when temperature is

a) increased
b) decreased

Answer 2

Kc

a) decreases
b) increases

Question 3

• when the forward reaction is endothermic what happens to Kc when temperature is

a) increased
b) decreased

Answer 3

Kc

a) increases
b) decreases

Question 4

• using Kc explain the shift in equilibrium when the concentration of a product is decreased

Answer 4

.

Question 5

• explain shift in equilibrium when pressure is increased (for a specific reaction: make one up)

2co + o2 —> 2co2

Answer 5
