Phase Equilibrium in Solutions Sections 11.5 and 11.6 Non-Volatile Solutes Raoult’s law- ideal solutions Colligative Properties: Vapor Pressure Lowering, Boiling Point Elevation, Freezing Point Depression, Osmotic pressure Volatile Solutes Raoult’s law - ideal solutions Henry’s Law linear behavior for dilute solute in region where Henry’s law works for solvent Distillations Ideal solutions Non-ideal solutions Negative Raoult’s deviation - maximum boiling azeotrope Positive Raoult’s deviation - minimum boiling azeotrope
Chapter 12 First Law First Law; Internal Energy equal heat plus work: E = q + w Energy is conserved - E system + surrounding = O Work: w = -P V(const P) - mechanical energy or macroscopic energy Heat: q = C T(const C) - temperature or microscopic energy Constant volume heat q v = E = C v T(const C v ) Enthalpy H = E + PV Constant pressure heat q p = H = C p T(const C p ) Thermochemistry; products - reactants for reactions, heats of phase transitions, standard state enthalpies, heats of formation, heats of combustion. Ideal Gas Equation of State: P = nRT/V Reversible processes, irreversible processes Ideal gas processes: Isothermal expansion-compression, Adiabatic expansion-compression

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
