Term
Equilibrium
Definition
When the rate of the forward reaction is equal to the rate of the reverse reaction
Term

K = [Products]x

         [Reactants]y

Definition
Equilibrium expression: x & y are the coefficients in the balanced equation
Term

Q = [Products]x

         [Reactants]y

Definition
Before equilibrium has been established: used to determine direction of reaction
Term
Q < K
Definition
Q must increase to reach equilibrium so reaction proceeds right
Term
Q > K
Definition
Q must decrease to reach equilibrium so reaction proceeds left
Term
Q = K
Definition
Reaction is at equilibrium, so reaction proceeds in both directions at the same rate
Term
K for a reverse reaction
Definition
Reciprocal of K
Term
K for an equation multiplied by a coefficient
Definition
K raised to a power
Term
K for a step-wise equation
Definition
Product of individual K’s
Term
Heterogeneous equilibrium
Definition
Reactants and products are in different states: Omit the solids and liquids b/c their concentrations are constant
Term
Concentration of a Reactant is increased
Definition
Reaction consumes reactant and shifts toward the right
Term
Concentration of a Product is increased
Definition
Reaction consumes product and shifts toward the left
Term
Product is removed
Definition
Reactions shifts right
Term
Increasing the temperature of an endothermic reaction
Definition
Shifts right
Term
Increasing the temperature of an exothermic reaction
Definition
Shifts left
Term
Kp = Kc(RT)Dn
Definition
Conversion between pressure and concentration
Term
Decreasing the volume at constant temperature
Definition
Shifts toward fewer moles of gases
Term
Increasing the volume at constant temperature
Definition
Shifts toward more moles of gases
