CHEM 1061 Chapter Notes - Chapter 5-7: Jmol, Ideal Gas Law, Endothermic Process
Document Summary
5-7 in chemistry; the molecular nature of matter and change. Includes: ideal gas law, effusion and diffusion, enthalpy, heat capacity, hess"s law, the. Rydberg equation, absorption and emission, de broglie wavelength, heisenberg"s uncertainty. Principle, energy levels of an atom, and quantum numbers. Pgas = patm - h where h is the height change of the liquid in the barometer in meters. Si pressure units: 1 bar = 1 e5 pa (where pa is pascals), 1 atm= 760 torr, 1 torr= 1mmhg. Standard temperature & pressure (stp): occurs at 0 c (273. 15 k), 1 atm (760 torr), volume = 22. 4 l. Ideal gas law: pv=nrt; for p=pressure in atm, v= volume in liters, n is the number of moles, t is the temperature in kelvins, and r is the universal gas constant (8. 314. This law does not work at extremely low temperatures and high pressures. Partial pressure: pa = xa * ptotal where xa is the mole fraction for element a.
