Dynamic Equilibrium
|
- forward and reverse reactions are going at the same rate |
|
Entropy |
|
|
Law of mass action
|
Keq = [C]^c[D]^d/[A]^a[B]^b |
|
Equilibrium Constant |
- Kc = Keq = [B][C]/[A]^2 |
|
Reaction Quotient
|
- how to measure the concentrations of all the reactants and products - concentrations of the products and reactants are not constant |
|
Relationships btwn Q and Keq
|
- Q = Keq, rxn is in dynamic equilibrium -Q> Keq --> forward rxn has exceeded equilibrium, greater concen of products |
|
Properties of the law of mass action
|
-Keq = temperature dependent - Larger the Keq = equilibrium is further to the right - equil constant for forward rxn = Keq, reverse rxn = 1/Keq |
|
Le Chatliers Principle
|
- if stress is applied to a system, the system shifts to relieve that applied stress |
|
Ideal Gas Law
|
-if the pressure increases, it will respond by decrease the amount of moles, therefore decreasing the pressure back to equilibrium |
|
Volume and Pressure
|
- system will react by increasing the number of gas moles to restore pressure |
|
Changes in temperature (Le Chatliers principle) |
exothermic: heat = product (H<0) |
|
Kinetic Product |
- "fast" products: require a lower free energy to form |
|
Thermodynamic product |
- free energy of the product is lower therefore more stable |
