Lecture

Chemical Equilibria and Reactivity

Description

This lecture covers the kinetic model of gases, based on four assumptions: random perpetual motion of gas particles, infinitesimally small particles moving in straight lines until elastic collisions, and no interactions other than collisions. It explains how gas temperature relates to the average particle speed and introduces the molar gas constant. The distribution of particle speeds in a gas, as described by Maxwell's law, is also discussed. The concepts of diffusion, effusion, and the Graham's law for effusion are explained. The lecture further delves into gas pressure, its relationship with particle speed and concentration, and the units of pressure measurement.
