Module 3: Chemical Equilibrium Flashcards
(5 cards)
1
Q
What’s a catalyst?
A
A substance which can increase the ROR without being used up. When in equilibrium, both forward and backward are increased at the same rate.
2
Q
Whats dynamic equilibrium?
A
A closed system where the rate of forward and backward reactions are equilibrium.
3
Q
What’s homogeneous equilibrium?
A
Equilibrium where all the reactants are in the same state.
4
Q
Whats Le chateliers principle?
A
A system in dyancim equilibrium can change, the position of equilibrium will change to minimize change.
Factors effecting this are:
Changing pressure, temperature, concentration
5
Q
What’s a closed system?
A
Energy cannot escape or leave the system
