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