Many students leave high school without being prepared for the
rigors of college chemistry. This course is designed to give students
the opportunity to review topics at a pace conducive to their level,
whether they are encountering the material for the first time or are
using the course as a refresher.
Allison Soult and Kim Woodrum bring their experience to the course covering kinetics, equilibrium, acid-base equilibria, aqueous equilibria and thermodynamics. Instruction consists of concepts, calculations, and video demonstrations of the principles being discussed. Practice problems and end of unit assessments will help students gauge their understanding of the material.
This ten-week course is comprised of five two-part units. Each part is intended to be completed in a week.
This unit examines the rates (speeds) at which reactions occur. You will examine the reactions on the macroscopic as well as molecular level and see how concentration and temperature play a role in the rates at which reactions occur.
This unit examines the quantitative and qualitative relationships between the relative amounts of products and reactants to see how far a reaction will proceed.
The concepts of equilibria from the previous unit are applied to acids and bases. Comparisons of strength and relationships between pH, pOH, and concentrations of H^+ and OH^- will be studied.
This unit continues and expands on the theme of equlibria. You will examine buffers, acid/base titrations and the equilibria of insoluble salts.
The overarching theme of thermodynamics is the prediction of whether a reaction will occur spontaneously under a certain set of conditions. Entropy and Free Energy are defined and utilized for this purpose.
This course is designed to look at the topics covered in advanced high school chemistry courses, correlating to the standard topics as established by the American Chemical Society. Engaging instruction and supplemental video demonstrations are designed to help prepare students for college level chemistry.
