Gibbs Free Energy (18.3.1) Flashcards
1
Q
• Spontaneity depends on change in enthalpy (∆H) and change in entropy (∆S).
A
• Spontaneity depends on change in enthalpy (∆H) and change in entropy (∆S).
2
Q
• Gibbs free energy change (∆G) is a thermodynamic state function that combines enthalpy and entropy, and reflects the spontaneity of a reaction. ∆G = ∆H – T∆S.
A
• Gibbs free energy change (∆G) is a thermodynamic state function that combines enthalpy and entropy, and reflects the spontaneity of a reaction. ∆G = ∆H – T∆S.
3
Q
• When ∆G 0, the reverse reaction is spontaneous.
When ∆G = 0, the reaction is at equilibrium.
A
• When ∆G 0, the reverse reaction is spontaneous.
When ∆G = 0, the reaction is at equilibrium.
