    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

    Ecell= Ecell - (0.0592 V / N)LogQ
    (Time)(Current) = Charge
    Common dry cell battery
    Car batteries
