11 equilib 2 Flashcards
1
Q
What is dynamic equilibrium?
A
When the forward reaction and backward reaction happen at the same rate so overall no change is occurring.
2
Q
What’s the equilibrium law?
A
A quantitive law for predicting the amounts of reactants and products when a reversible reaction reaches a state of dynamic equilibrium.
3
Q
How do you write Kc expression when all states are same?
A
1) products over reactants
2) have number of moles as power
4
Q
Why do solids not appear in Kc?
A
Pure solids have a constant concentration, so their value is incorporated into the value for the equilibrium constant.
5
Q
Why are (aq) and (l) included in the same Kc?
A
As they’re same states but different phases
