CHEM 102 Lecture Notes - Lecture 30: Rate Equation, Vant (Band), Solution Process
Document Summary
Chapter 10: phase diagrams & types of solids. Chapter 11: colligative properties ( t & osmotic pressure) Chapter 12: rates of reaction, factors that affect rate. The more structurally complex the molecules are and the stronger the imf"s between them, the more difficult it is to move past each other (greater viscosity). Cohesive forces- various imfs between molecules of a substance. Capillary action-when molecules creep- cohesion holds these molecules together (against gravity) Vapor pressure is determined by imfs and temperature- for a liquid- only temperature determines vapor pressure. Net dipole movement exists in substances that are polar. Relate how viscosity for car oil is during summer and winter seasons. Vaporization-liquid to gas and condensation-gas to liquid- dynamic equilibrium when they are equal to one another. Stronger imf means vapor pressure lowest meaning that vaporization rate is slowest. The normal boiling point= boiling point when pressure = 1 atm.
