Équilibria Flashcards
How does temperature affect kc
- Valid for 1 temp
- If temp change causes equilibrium to shift right Kc will increase
- if temp change causes equilibrium to shift left Kc will decrease
What are the units of Kc
Moldm-3
What is le châteliers principe
If a reaction in equilibrium is subjected to a change the system will counteract the change by shifting the position of the equilibrium
What happens if you increase if you Increase the reactants in a reaction
The equilibrium would shift to the left to counteract the change
So more of the product is made
What is homogenous equilibrium
Reactants and products in the same state
What happens if we increase pressure in the equilibrium
If we increase pressure the system will move to side with less moles of gas
What will happen if we increase the temperature of the system
The equilibrium will shift to reduce the temperature
So it will shift in the endothermic direction
What happens if we decrease the temperature of a system
It will shift in the exothermic direction which will Increase the temperature
Do catalysts have an effect on equilibrium
No, because they catalyst will speed up the rate of the forward and backward reaction of the system
What will happen to KC if equilibrium shifts to the right
Kc will increase
What will happen to Kc if equilibrium shifts left
KC will decrease
How does concentration affect KC
It does not
