Le Chatelier's Principle (pressure changes)
Le Chatelier's Principle (pressure changes)
Equilibrium shifts to oppose the pressure change
Increased pressure effect on equilibrium
Increased pressure effect on equilibrium
Equilibrium shifts to side with fewer moles of gas
Decreased pressure effect on equilibrium
Decreased pressure effect on equilibrium
Equilibrium shifts to side with more moles of gas
Why shift to fewer moles opposes pressure increase
Why shift to fewer moles opposes pressure increase
It reduces the overall pressure of the system
Types of reactions affected by pressure changes
Types of reactions affected by pressure changes
Reactions involving gases
High pressure: equilibrium direction
High pressure: equilibrium direction
Towards fewer moles of gas
Low pressure: equilibrium direction
Low pressure: equilibrium direction
Towards more moles of gas
