Le Chatelier's Principle

When a system at equilibrium is disturbed, it shifts to partially counteract the change.

Add reactant/remove product: Shift right (toward products).
Add product/remove reactant: Shift left (toward reactants).
Increase temp (exothermic): Shift left (treat heat as product).
Increase temp (endothermic): Shift right (treat heat as reactant).
Decrease volume / increase pressure: Shift toward fewer moles of gas.
Catalyst: No shift — speeds both directions equally.
Add/remove solid or liquid: No shift (not in Keq).
