Kc and Kp

Question 1

If Kc = 1 (2 points)

Answer 1

1. Equilibrium is halfway in between reactants and products

2. Concentration of reactants and products is the same

Question 2

If Kc > 1 (2 points)

Answer 2

1. Equilibrium lies to the right and the reactionfavours the products
2. Concentration of products > reactants

Question 3

If Kc < 1 (2 points)

Answer 3

1. Equilibrium lies to the left and the reaction favours the reactants
2. Concentration of reactions > products

Question 4

Kp compares the

Answer 4

partial pressure of chemical species in the equilibrium

Question 5

Homogeneous Equilibrium

Answer 5

is when all reactants and products involved in an equilibrium reaction are in the same state

Question 6

Heterogeneous Equilibrium

Answer 6

is when reactants and products involved in an equilibrium reaction are in different states

Question 7

What is included in the Kc formula for homogeneous equilibrium

Answer 7

All reactants and products as they are in the same state (so can be liquid, solid, gases etc)

Question 8

What is included in the Kc formula for heterogeneous equilibrium

Answer 8

Only reactants and products in the gaseous or aqueous states can be included

Question 9

What has an affect on the value of Kc?

Answer 9

Temperature

Question 10

What doesn’t have an affect on Kc? (3 points)

Answer 10

1. Changes in pressure
2. Changes in concentration
3. Catalyst
