Study Notes
Kinetic Molecular Theory and Phase Diagrams in Chemistry
- Kinetic Molecular Theory describes the motion of molecules in different phases: solid, liquid, and gas, based on their kinetic energy and intermolecular attraction.
- Gas molecules are in random, constant motion, moving in a straight line until they collide with something, and have no attraction to other gas molecules or their container.
- KMT can be described mathematically through the ideal gas law, Boyle's law, and Charles' law, and the kinetic energy of the molecules can be calculated.
- A phase diagram graphically represents the temperature and pressure combinations of a substance for each state of matter, including the triple point and critical point.
- Phase changes occur when energy and pressure are added or removed from a system, leading to processes such as evaporation, condensation, sublimation, deposition, freezing, and melting.
- Supercritical fluid exists past the critical point, where the boundary between a liquid and a vapor is gone, and the vapor and liquid are indistinguishable.
- Chemical reactions are categorized into five types: combination, decomposition, single-replacement, double-replacement, and combustion, each involving specific reactants and products.
- During a chemical reaction, matter is neither created nor destroyed, and energy may be absorbed (endothermic) or released (exothermic).
- The mole is a unit of measurement representing 6.02 x 10^23 particles, and Avogadro's number is used to calculate the number of particles when given the number of moles.
- Molar mass is the mass of one mole of a substance, and it can be used to calculate the number of moles of a substance given the number of particles.
Kinetic Molecular Theory and Gas Properties
- Dalton developed kinetic molecular theory of gases based on properties of gases
- Kinetic molecular theory summarized in 5 points, including random motion, no attractive forces, and elastic collisions
- Dalton's generalizations led to the concept of ideal gases
- Atmospheric pressure caused by gas particle movement and collisions
- Barometers measure atmospheric pressure and have various units including mmHg, Pascal, Psi, Torr, and Atmosphere
- Density is the mass to volume ratio, with gases being highly responsive to temperature and pressure changes
- Ideal gas law (PV = nRT) describes gases with negligible volume and intermolecular forces
- Pressure alters gas behavior, and partial pressures are component pressures in a gas mixture
- The law of partial pressures formula calculates total pressure in gas mixtures
- Vapor pressure is associated with a liquid turning into a gas
- Moles and mole ratio are used to understand the effects of pressure on gas behavior
- Maxwell and Boltzmann developed the Maxwell-Boltzmann distribution to describe gas particle velocities and kinetic energy distribution
