G and K
-
If at equilibrium, dG (ns) = 0, so equation becomes:
-
Gases use partial pressure, solutes use molarity
WHEN G IS LOWEST, reaction is at equilibrium...reaction always gravitates towards lowest G possible.
Enthalpy vs. Entropy
Enthalpy tends to decrease in a process (to surroundings) while entropy increases; spontaneity follows decrease/increase respectively
-
Entropy is actually a measure of possible microstates; think about it in terms of energy or mass DISPERSAL though
-
-
-
Misc:
Spontaneous processes can have a high activation energy! They it just means that they will be slow at a normal temp
In any spontaneous process, entropy of universe increases; in a nonspontaneous process, dS of universe is ZERO
If all else is similar and moles of gas doesn't change, then the entropy change is indeterminate
