Kc constant

Question 1

What is Kc?

Answer 1

The equilibrium constant
Gives us an idea of how far left or to the right the position of equilibrium is

Question 2

What 2 methods are used to calculate the Kc?

Answer 2

Heterogeneous equilibrium
Homogeneous equilibrium

Question 3

Homogeneous equilibrium

Answer 3

Calculating the Kc when all reactants and products are in the same state

Question 4

What values are used in homogeneous equilibrium?

Answer 4

ALL

Question 5

Kc expression

Answer 5

[Conc of product]
————————
[conc of reactant]
May be multiple
To the power of the stoichoometry

Question 6

Heterogeneous equilibrium

Answer 6

Calculating the Kc when not everything is in the same physical state

Question 7

What values are used in heterogeneous equilibrium?

Answer 7

DONT INCLUDE PURE LIQUIDS (l)
DONT INCLUDE SOLIDS (s)

Question 8

Why not use liquids or solids in equilibrium constant?

Answer 8

Because their concentrations stay constant throughout the reaction

Question 9

What factors affect the equilibrium constant?

Answer 9

None of them except temperature
