What is the symbol for an Equilibrium constant?
|
Kc
|
|
|
|
What is the formula for the Law of Mass Action?
|
Kc= [C]◇ + [D]◇/[A]◇ + [B]◇
(the diamonds in this formula symbolizes exponents) |
|
|
|
The only caveat is that tge reactants and products must be either _______________, in order to be included in the expression for Kc.
|
Gases or in a solution
|
|
|
|
Describe the magnitude of Kc.
|
If Kc is very large for a certain reaction, it means that you have mostly product, and very little reactant. If the Kc is very small, you will have mostly reactants and very little product.
|
|
|
|
When you know the Kc, and you want to find Kp, what is the formula we use?
|
Kp= Kc (RT)▲n
(▲n= moles product - moles reactant) |
|
|
|
Since solids and liquids does not fill their containers, d/MW= constant, meaning ______ is constant?
|
Molarity
|
|
|
|
Suppose we encounter a reaction in progress, how would ee know if its going to the left (←) or right (→)?
|
If Qc = Kc (equilibrium)
If Qc < Kc (to the right) ↑pro ↓rxn If Qc > Kc (to the left) ↓pro ↑rxn |
|
|
|
What is Le Châtelier's princple?
|
If a system (i.e. a reaction) at equilibrium is disturbed, the position of equilibrium will shift, so as to minimize the disturbance.
|
|
|
|
What are the disturbances entailed in Le Châtelier's principle?
|
-Adding or removal of products or reactants.
--Gasses- increase or decrease in pressure or volume. ---Changes temp or catalyst included. |
|
|
|
Based on Le Châtelier's principle, adding or removing a product or reactant, what will occur?
|
Add a reactant-rxn shifts right (→).
Remove reactant- rxn shifts left (←). Add a product- rxn shift left (←). Remove product- rxn shift right (→). |
ONLY FOR GASES OR SOLUTIONS!
