Chapter 5 Chemistry Outline Lecture Ch. 5 Gases Chem behavior is based upon comp but all gases have many phys similarities Pressure = Force/Area Barometer- measures atmospheric pressure Gas Laws- Physical behavior of gases is defined by four variables, P V T n Boyle’s Law- (T and n constant) P1V1 = P2V2 Charles’s Law = (P and n are fixed) V1/T1 = V2/T2 (T in Kelvin) Avogadro’s Law = (P and T fixed) V1/n1 = V2/n2 Standard Molar Volume At STP (0 C and 1 atm) 1 mol of any gas occupies 22.4141 L Combined Gas Laws PV = nRT R = the universal gas constant Molar Mass and density m/v = P MM / RT = d Dalton’s Law of partial pressure Each gas in a mixture exerts a partial pressure Total Pressure = the sum of the partial pressures Mole Fraction, X Find portion chem entity makes up in eq’n and multiply by total pressure to find partial pressure Kinetic Molecular Theory Postulates – Volume of a gas is neglible, Gas particles are in constant, random, straight-line motion; gas particles collisions are elastic, total kinetic energy is constant

    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.
