Part I(Pines) • Stoichiometry(chemical arithmetic)
• Atomic and Molecular Structure(quantum theory)
• States of Matter(gas, liquid, solid)
Part II(Saykally) • Energetics(1st Law, enthalpy, work, heat)
• Spontaneity(2nd Law, entropy, free energy)
• Equilibrium(Gibbs free energy, Keq, wet chemistry)
Second Law of Thermodynamics
-The Disorder of the Universe Increases in any Real Process
-Some Energy is Used to Create Disorder
Disorder = Entropy Universe = System + Surroundings Real = Finite Time
-Heat Flows from Hot to Cold(Clausius statement)
