Unit 7: Equilibrium Flashcards
(20 cards)
Ksp
is solubility product constant, which has no denominator because reactants are solids.
Law of Mass Action
The is the equilibrium expression that determines the relationship between reactant and product concentrations.
Kc
is constant for molar concentrations.
Q
reaction quotient
Le Chatelier’s Principle
When a stress is added to a reaction, the equation will change to adjust for the stress and revert back to equilibrium.
not shift
If Q and K are equal, the reaction will
shift to the right
If Q is less than K, the reaction will _
shift to the left
If Q is greater than K, the reaction will _
products
If a reaction shifts to the right it will make more _
reactants
If a reaction shift to the left, it will make more
temperature
Only when _ stress is added will the equilibrium constant
Ka
is the acid dissociation constant.
concentration and pressure
When is changed, the equilibrium constant will eventually revert to the original value
equilibrium reactions
In , the reaction is reversible, where the reactants from products and then go back to reactants constantly.
Ksp
is the measurement of how much a salt dissolves in a solution.
Common Ion Effect
When an element is added to a solution with a salt, the salt equilibrium will change if the element is similar.
more mole of aqueous
If water evaporates from a solution with a salt, the reaction will shift to the side with _
less moles of aqueous
If water is added to a solution with a salt, the reaction will shift to the side with _
less mole of gas
If pressure is added to a container, the reaction will shift to the side with
more moles of gas
If pressure is removed from a container, the reaction will shift to the side with
