Equilibria Flashcards
(4 cards)
1
Q
What is dynamic equilibrium?
A
- both forward & backward reactions are happening at same rate
- concentrations of reactants & products remain constant
- happens in closed system
2
Q
What happens to the equilibrium when you change pressure?
A
- increasing pressure: moves to side with fewer moles
- decreasing pressure: moves to side with more moles
3
Q
What happens to the equilibrium when you change temperature?
A
- increasing temperature: moves to endothermic side
- decreasing temperature: moves to exothermic side
4
Q
What happens to the equilibrium when you add a catalyst?
A
no change
rate at which it reaches equilibrium is much faster
