Description:
Continuation of CHM 151. Includes emphasis on certain chemical concepts such as chemical kinetics,
equilibrium, acids and bases, thermodynamics, and electrochemistry.
Prerequisite(s): With a grade of C or better: MAT 151 and either CHM 151/151LB or CHM151IN.
Corequisite(s): CHM 152.
Information: IN is the integrated version of the course with the lecture and lab taught simultaneously.
Student Learning Outcomes:
Upon successful completion of the course, the student will be able to:
1.
2.
3.
Define the rate of a reaction and the rate law, determine the components of the rate law, and
describe the effects of concentration, temperature and catalysts on the rate of a reaction.
Write and calculate equilibrium constants for a chemical reaction, calculate equilibrium
concentrations from initial concentrations, apply Le Chatelier's principle to a chemical reaction
and predict how changes in concentration, temperature, pressure, and volume influence the
equilibrium system.
Distinguish between Arrhenius and Bronsted acids and bases, identify conjugate acid/base pairs,
predict the direction of a neutralization reaction, determine dissociation constants (Ka,Kb), pH
and pOH in aqueous solutions, and relate molecular structure to acid strength.
