Equilibrium constant Kc
Physical
AS
Equilibria & Le Chatelier
AQA Content
construct an expression for Kc for a homogeneous system in equilibrium
calculate a value for Kc from the equilibrium concentrations for a homogeneous system at constant temperature
perform calculations involving Kc
predict the qualitative effects of changes of temperature on the value of Kc
Specification Notes
The equilibrium constant Kc is deduced from the equation for a reversible reaction.
The concentration, in mol dm–3, of a species X involved in the expression for Kc is represented by [X]
The value of the equilibrium constant is not affected either by changes in concentration or addition of a catalyst.
