Q

What is the le Chateliers principle

A

The idea that if you change the conditions of a reversible reaction at equilibrium the system will try to counter act the change

Q

What happens if you decrease the temperature

A

The equilibrium will move in the exothermic direction to produce more heat
This means you’ll get more products for the exothermic reaction and fewer products for the endothermic reaction

Q

What will happen if you raise the temperature

A

The equilibrium will move in the endothermic direction to try and decrease it
You will get more products for the endothermic reaction and fewer products for the exothermic reaction

Q

What happens if you increase the pressure

A

The equilibrium tries to reduce it and it moves in the direction where there are fewer molecules of gas

Q

What happens if you change the concentration of either products or reactants

A

The system will no longer be at equilibrium so the system reacts by trying to bring itself back to equilibrium again
