Which type of reaction is affected by pressure changes at equilibrium?
Which type of reaction is affected by pressure changes at equilibrium?
Reactions involving gases
What happens when pressure is increased in a gaseous equilibrium system?
What happens when pressure is increased in a gaseous equilibrium system?
Shifts to side with fewer moles of gas
What happens when pressure is decreased in a gaseous equilibrium system?
What happens when pressure is decreased in a gaseous equilibrium system?
Shifts to side with more moles of gas
What happens if both sides of an equilibrium have equal moles of gas?
What happens if both sides of an equilibrium have equal moles of gas?
Pressure change has no effect
In , how many moles of gas are on the left?
In , how many moles of gas are on the left?
4 moles
In , how many moles of gas are on the right?
In , how many moles of gas are on the right?

In ammonia production, what happens when pressure is increased?
In ammonia production, what happens when pressure is increased?
Equilibrium shifts right, more ammonia
In ammonia production, what happens when pressure is decreased?
In ammonia production, what happens when pressure is decreased?
Equilibrium shifts left, less ammonia
Why does increasing pressure shift equilibrium to the side with fewer moles of gas?
Why does increasing pressure shift equilibrium to the side with fewer moles of gas?
Reduces pressure by decreasing gas molecules
According to Le Chatelier's Principle, how does equilibrium respond to pressure change?
According to Le Chatelier's Principle, how does equilibrium respond to pressure change?
Shifts to counteract the change
