19.1 Equilibrium Constant Kc Part 2

Question 1

How is Kc calculated?

Answer 1

[products] / [reactants] at equilibrium

Question 2

What does value of Kc show?

Answer 2

Larger value - closer to products
Smaller value - closer to reactants

Question 3

Answer 3

Homogeneous
Heterogeneous

Question 4

Homogeneous equilibrium

Answer 4

Equilibrium species all have same state

Question 5

Heterogenous equilibrium

Answer 5

Equilibrium species have different states

Question 6

How is Kc calculated for heterogenous equilibria?

Answer 6

Concentrations of solids and liquids are omitted
Only concentrations of (g) and (aq) used
