LT#2: Describing Equilibria Flashcards
1
Q
Define Equilibrium
A
Forward and reverse reactions occur simultaneously at the same speed.
2
Q
Describe the Conditions necessary to achieve equilibrium
A
- Dynamic change at molecular level, but no change at the macroscopic level.
- Need a closed system.
- Can be reached from either direction.
3
Q
At equilibrium, what happens to the amount of reactants and products.
A
They stay constant over time.
4
Q
Does being at equilibrium mean the forward and reverse rxn have the same spontaneity?
A
No, just same speed.
5
Q
When the forward rxn is more spontaneous, what happens at equilibrium?
A
More products are in the system than reactants.
6
Q
When the reverse rxn is more spontaneous, what happens at equilibrium?
A
More reactants are in the system than products.
