K & Q & Ksp

K>1

• products are favored

• shifts to the right (favors foward)

• mostly products at equilibrium

K<1

• reactants are favored

• shifts to the left (favors reverse)

• mostly reactants at equilibrium

K=1

• balanced reaction

Q>1

• alot of product

• Same as K>1

Q<1

• lots of reactant

• same as K<1

Q=1

• balanenced

K>Q

• not enough product (to much reactant)

• shifts to the right

K<Q

• not enough reactants (to much product)

• shift to left

K=Q

• reaction is at equilibrium

increase reactants?

• shift right

• increase forward rate

• no change on Keq

decrease reactants?

• shift left

• increases reverse rate

• no effect on Keq

increase products?

• shift left

• increases reverse rate

• no effect on Keq

decrease products?

• shift right

• increase forward rate

• no effect on Keq

increase pressure (decrease volume)?

• only effects gasses

• shift towards side w fewer moles of gas

• increases rate bc collisions occur more frequently

• no effect on Keq

decrease pressure (increase volume)?

• only effects gasses

• shifts towards side w more moles

• slows rate bc less collsions

• no effect on Keq

increase tempature (endothermic)

• shift to right

• Keq increases

decrease temperature (endothermic)

• shift to left

• Keq decreases

increase temperature (exothermic)

• shift left

• Keq decreases

decrease temperature (exothermic)

• shift to right

• Keq increase

Ksp > Q

• shift right

• no precipitate

Ksp < Q

• shift to left

• precipitate forms

What is the only thing that can effect Keq

increase/ decrease in temperature

Catalalyst?

does not cause shift in equilibrium, instead it allows the reaction to reach equilibrium faster.
