Equilibrium Flashcards
What is equilibrium?
When the rates of the forward and reverse reactions are equal
What do you call a reaction that does not stop when equilibrium is attained?
A dynamic process
What can you do to change the position of the equilibrium?
Change concentration/ temperature/ pressure
In what ways should you change the concentration to move the equilibrium to the right-hand side?
- increase the concentration of reactants
- decrease the concentration of products
In what ways should you change the concentration to move the equilibrium to the left-hand side?
- decrease the concentration of reactants
- increase the concentration of products
An increase in temperature will favour which reaction in equilibrium?
The endothermic reaction
A decrease in temperature will favour which reaction in equilibrium?
The exothermic reaction
Where does the equilibrium move if there is an increase in temperature?
Moves to the left-hand side
Where does the equilibrium move if there is a decrease in temperature?
Moves to the right-hand side
An increase in pressure causes the equilibrium to…
Shift to the direction which reduces the number of gas molecules
A decrease in pressure causes the equilibrium to…
Shift to the direction which increases the number of gas molecules
What effect will a catalyst have on equilibrium?
It will have no effect.
Adding a catalyst simply allows equilibrium to be attained faster
