Suggested Curriculum for General Chemistry
Copyright (c) RDMCHEM LLC 2019,2020
Computational chemistry is a powerful tool for introducing, exploring, and applying concepts encountered throughout the chemistry curriculum. The aim of these lessons is to provide students and/or instructors ways to interact with selected topics using the QuantumChemistry package exclusively within Maple with no need to collate multiple software packages! Lessons are written to emphasize learning objectives rather than Maple coding. However, in order to show students and instructors how the calculations are set up, each lesson contains the Maple syntax and coding required to interact with the selected topic. In some cases, questions are asked of the student with the answer provided as a subsection. As such, each lesson can be used 'asis' or modified as desired to be used by students in a classroom setting, laboratory setting, or as an out of class guided inquiry assignment.
While lessons are largely independent of each other and may be done in any order, the numbering follows a traditional 'thermodynamics first' approach in which the first 9 lessons cover atomic structure and chemical bonding, ideal and real gases, and thermodynamics. These lessons are followed by 6 lessons that cover atomic structure and chemical bonding from a quantum perspective. An 'atoms first' approach to general chemistry that emphasizes the quantum description of matter and energy can be established by covering Lessons 13, Lessons 1015, and finally, Lessons 49. Lesson 1 (Atomic Structure) explores the structure of the atom, both its discovery and its science. Lesson 2 (Chemical Bonding) teaches the nature of the chemical bond between atoms. Lesson 3 (VSEPR) explains molecular geometries from valenceshell electronpair repulsion theory. Lessons 4 and 5 (MaxwellBoltzmann Distribution and Boltzmann Distribution) investigates the MaxwellBoltzmann distribution of molecular speeds in ideal gases as well as the more general Boltzmann distribution. Lesson 6 (Heat Capacity) computes and compares heat capacities of ideal and real gases. Lessons 79 (Enthalpy, Entropy and Free Energy, and Thermodynamics of Combustion Reactions) calculate thermodynamic functions such as internal energy, enthalpy, entropy, and Gibbs free energy. Lessons 10 and 11 (Blackbody Radiation and Photoelectric Effect) correspond to early experiments related to the quantization of energy. Lesson 12 (Particle in a Box) involves the Schrödinger equation and its solutions. Lesson 13 (Periodic Trends in Atomic IEs) considers periodic trends in ionization energies of atoms by calculating atomic orbital energies of neutral and cation species explicitly. Lesson 14 (Molecular Orbitals) focuses on molecular orbital theory as applied to hydrogen fluoride. Lesson 15 (Koopman's Theory and Molecular IEs) also relies on the calculation of periodic trends in ionization energies but uses Koopman's approximation method for determining IEs.
