Equilibrium constant (Kc) Flashcards
1
Q
What is Kc called?
A
Equilibrium constant
2
Q
What is the equation for Kc?
A
Kc = [C]c x [D]d / [A]a x [B]b
3
Q
What does the [A] stand for?
A
Concentration of chemical A in
moldm-3
4
Q
What does Kc show?
A
How far towards the right or left a reaction lies when a reaction is at
equilibrium
5
Q
What does a larger value for the Kc tell us?
A
The more the reaction has gone to completion
The more the reaction favours completion
6
Q
What is favoured when the the Kc is large and greater than 1?
A
Products are favoured
Equilibrium lies towards the right
7
Q
What is favoured when the the Kc is small and less than 1?
A
Reactants are favoured
Equilibrium lies towards the left
