The Equilibrium Constant, Kc Flashcards
1
Q
What is Kc?
A
The value of Kc is a useful measure of the position of equilibrium.
2
Q
What are the 4 values Kc can have?
A
Kc > 1
Kc»_space; 1
Kc < 1
Kc «_space;1
3
Q
What does Kc > 1 mean?
A
Kc is bigger than 1
Equilibrium lies towards the products.
4
Q
What does Kc»_space; 1 mean?
A
Kc is much bigger than 1, greater than 10x10
Equilibrium lies on the far right, so far the reaction appears to have gone to completion.
5
Q
What does Kc < 1 mean?
A
Kc is smaller than 1
Equilibrium lies to the left
6
Q
What does Kc «_space;1 mean?
A
Kc is much smaller than 1 (less than 10x-10)
Equilibrium is on the far left and reaction appears to have not occurred.
7
Q
What does is mean when Kc is close to one?
A
Similar amount of reactant and products.
