Equilibrium Flashcards
To shift equilibrium we can change
Temperature pressure concentration
Le chateliers principle states
The equilibrium will shift to try and oppose a change that has been made
Forward EXO
Increase temp
Favour, Endo reaction backwards
Takes in heat
Equilibrium shifts to the left
Forward EXO
Decrease Temp
Favour XO reaction forward, gives out heat
Equilibrium shift to the right
Forward Endo
Increase temp
Favour, Endo forward, absorb, heat energy
Equilibrium shift to the right
Forward Endo
Decrease temp
EXO favoured backwards, gives out heat
Equilibrium shift to the left
Forward more moles of gas
Increase pressure
Equilibrium shift to the left
Fewer gas particles
Oppose change
Decrease pressure
Forward more moles of gas
Decrease pressure
Equilibrium shift to the right
More gas particles
Oppose change
Increase pressure
Forward, fewer moles of gas
Increase pressure
Equilibrium shifts to right
Fewer molecules of gas
Oppose change
Forward reaction, fewer miles of gas
Decrease pressure
Equilibrium shift to the left
More molecules of gas
Oppose change
Increase concentration of reactant
Equilibrium shifts, right
Increase product
Turn A into product
Increase concentration of product
Equilibrium shifts left
Increase reactants
Use C turn into reactant
Decrease the concentration of reactant
Equilibrium shift left
Replace reactants
Reactants increase
Decrease the concentration of product
Equilibrium shifts, right
Increase products
Replace C
Does a catalyst change the equilibrium of a reaction
No
