Class notes General Chemistry I (CE-111)

Chapter 10 - Gases The following topics are covered: - Calculate pressure and convert between pressure units with an emphasis on torr and atmospheres. • Calculate P, V, n, or T using the ideal-gas equation. • Explain how the gas laws relate to the ideal-gas equation and apply the gas laws in calculations. • Calculate the density or molecular weight of a gas. • Calculate the volume of gas consumed or formed in a chemical reaction. • Calculate the total pressure of a gas mixture given its partial pressures or given information for calculating partial pressures. • Describe the kinetic-molecular theory of gases and how it explains the pressure and temperature of a gas, the gas laws, and the rates of effusion and diffusion. • Explain why intermolecular attractions and molecular volumes cause real gases to deviate from ideal behavior at high pressure or low temperature.
