1
What's dynamic equilibrium?
when the forward and backwards reaction are at the same rate and so AMOUNTS of reactants and products stays the same
2
What is LeChatelier's Principle?
if a change is imposed in a system in equilibrium the system moves to counteract the change.
3
effect of increase concentration in reaction
favours side with less moles
4
effect of increase pressure in gases in reaction
favours side with less moles
5
effect of temperature on equilibrium?
Increase favours Endothermic
Decrease favours Exothermic
Decrease favours Exothermic
6
what is kc
concentration of products / concentration of reactants
7
unit for concentration
mol dm^-3
8
what changes kc?
+ temperature = increase kc
- temperature = decrease kc
- temperature = decrease kc
9
tip with kc with moles
If both sides have the same amt of moles you can just use moles for Kc equation instead of concentration
