1. A brief outline of what materials will be covered
1. When Delta G is used:
- to predict the direction of a chemical reaction under two conditions
o Constant temperature
o Constant pressure
2. Equation and units
-Go over the equations and what each letters represent (along with their appropriate
units)
The Gibbs Free Energy Equation:
AG
change in free energy
ΔΗ
change in enthalpy
TAS
(temperature) change in entropy
Or at standard state:
ΔG ΔΗ-ΤΔS
Gibbs Free Energy and Equilibrium:
AG° = –RT In K
where:
G is Gibbs Free Energy (SI unit: kj)
Tis temperature (SI unit: kelviri)
S is entropy (SI unit: joule/kelvin)
H is the enthalpy (SI unit: joule)
