Law of MASS ACTION |
Keq= [Cc][Dd]/[Aa][Bb] |
|
|
At equilibrium, the rate of forward=reverse reaction. True or False? and the entropy is at maximum and Gibbs free energy is a minimum? |
True for both |
|
|
How do we calculate the TOTAL equilibrium constant for the overall reaction. NOTICE THE EQUILIBRIUM CONSTANT, not the rate of LAW |
Picture of equation, pg182 |
|
|
what is the reaction quotient and how is it different from the Keq of a reaction |
-the Keq describes the position of equilibrium with constant concentrations of products and reactants all throughout the reaction. -the Reaction quotient does not have equal conc. of reactants and products. |
|
|
relationship between Q and Keq, given that both are the same equations |
-when Q -When Q=Keq, the reaction is at equilibrium. -When Q> Keq, the reverse reaction is happening towards equilibrium. |
|
|
what are some things that do not appear in the expression of the Keq, law of mass action equation. |
- liquids such as [H2o] liquid. -Solids as well. Only aqueous and gaseous show in expressing keq= [c] [d]/ [a] [b] |
|
|
Le chatelier's principle |
when applying stress on the system with equilibrium, the system's equilibrium will shift to relieve the stress. |
|
|
Changes in pressure and volume for chatlier's priciple |
in an equation like this *this is at equilibrium to begin with*. N2+3H2---> (and <---) 2NH3. 4 moles of reactants and 2 moles products. ****Under pressure and less volume you want to form the 2 mole product (think of less space so less moles works). ***Under no pressure, and more volume, you want to go back to the 4 moles because there is more room to fill up. |
