Equilibrium Flashcards
At the point of equilibrium…
The rates of the forward and reverse reactions are equal
At equilibrium, the concentrations of reactants and products will…
NOT be equal
What is Kc used for?
Used to identify whether the equilibrium favours the forward reaction or reverse reaction
What is solubility
Solubility is a concentration of the maximum amount of solute that will dissolve.
What is a saturated solution?
A solution that is at the solubility limit, no more will dissolve.
What is Ks?
Ks is an equilibrium constant that is calculated using the concentrations at the solubility limit.
It is not insoluble, it is
Sparingly soluble
Equilibrium constant expression is..
Concentration of products divided by concentration of reactants
How to convert between g/L and mol/L
N=m/M
Ks value is always calculated using…
mol/L
In a 1:1:1 mole ratio then Ks=
S^2
Le Chateliers Principle
When a system at equilibrium is disturbed, the system will act to restore equilibrium.
