​Learning objectives -  Be able to explain, use, calculate, apply, & analyze the following: 
​
Thermodynamics: ∆G and  ∆S  Key points
  1. Thermodynamically favorable (spontaneous) reactions have a (-) ∆G.
  2. Reactions with (-) ∆H and (+)∆S are ALWays thermodynamically favorable....  "Enthalpy driven & entropy driven"
  3. Reactions that increase the # of moles of gas have a (+)∆S
  4. If ∆G is (-) , then Keq > 1
  5. ∆H and ∆S are usually NOT given in the same units!! When using ∆G° = ∆H° - T∆S°, measure sure they match units.
  6. ∆G = 0 at equilibrium
  7. When using ∆G° = -RT lnK, the value for R is 8.314 j/mol K so the answer for ∆G will be in the units of Joules
