Gibb's Free Energy Flashcards
1
Q
What is the equation for Gibb’s free energy? Define all terms.
A
∆G = ∆H - T∆S
∆G = change in Gibbs free energy
∆H = change in enthalpy
T = temperature
∆S = change in entropy
2
Q
If ∆G < 0 the process is what?
A
Spontaneous/favourable.
3
Q
If ∆G = 0 the process is what?
A
At equilibrium.
4
Q
If ∆G > 0 the process is what?
A
Nonspontaneous/unfavourable.
5
Q
If ∆H < 0 the process is what?
A
Favourable.
6
Q
If ∆H > 0 the process is what?
A
Unfavourable.
7
Q

A
Unfavourable.
8
Q
If ∆S > 0 the process is what?
A
Favourable.
