Equilibrium Flashcards
Dynamic Process
the reaction keeps going after equilibrium is reached
“Preferred reaction”
Which reaction shift makes the most product
Equilibrium Constant (K)
Products/reactants
- can also tell is how to reach equilibrium
- ONLY true at Equilibrium
If K > 1
Forward is Preferred
If K
Reverse is preferred
Q is used when….
- questioning where you are in a reaction
- Is true at ALL times
Q>K
Reverse must occur for equilibirium
Q
Forward must occur for equilibirium
Q=K
Has already reached equilibrium
Le Chatlier’s Principle
when a system at equilibrium experiences a “stress”, the position of equilibrium will “shift” to relieve the “stress” and a new equilibrium will be established
Changing Concentration
See-Saw
Changing Pressure
Low pressure favors high moles
High pressure favors low moles
Catalyst
No impact on the “shift”
Temperature
Increased Heat = reverse
Decreased Heat = Foward
Positive Enthalpy
Endothermic reaction (heat is reactant)
