Spontaneous process
Entropy (S): A measure of disorder
Determining a + or – entropy for a situation
Str = Htr/Ttr
Srxn = [Sproducts - Sreactants]
G = H - TS
For the following are they spontaneous at all temperatures, low tem, high temp or non-spontaneous at all temperatures.
Grxn = [Gf products - Gf reactants]
Grxn = - RT LnKp
Redox Reactions
Steps to balancing a redox reaction
Galvanic cells
Cell diagrams: Shows the components of an electrochemical cell in a symbolic way.
Ecell = E(cathode) + E(anode)
Standard hydrogen electrode (SHE)
G = -NFEcell
Ecell = (0.025693 V / N)LnKeq
