Number density, speed and collisions between gaseous molecules in pure gases and in mixtures, collisions with walls and surfaces, and mean free paths, are calculated. Perfect gases are always assumed. Finally, section 8 deals with Chemical Thermodynamics. The 40-page section contains problems with work and heat, Gibbs energy, enthalpy and entropy changes during chemical reactions, heat capacities, equilibrium constants, yields, pH and solubility. In Figure 4.1, page 49, the names of the colors in the visible spectrum are upside down.
Equilibrium constants are dimensionless.
However, their number is too limited. Overall, new students in chemistry will find the workbook useful to review basic concepts and develop abilities in learning how to solve problems in introductory physical chemistry. All rights reserved.
