CHEM 1042 - Principles of Chemistry II Credits: 5
Hours/Week: Lecture 5 Lab 3
Course Description: This course is a continuation of CHEM 1041 . Students will investigate intermolecular forces, solid state structure, properties of solutions, chemical kinetics, chemical equilibria, acids and bases, electrochemistry, chemical thermodynamics, and nuclear chemistry. The laboratory work emphasizes observation, organization of data, analysis of data, and experimental design. This course is intended for students who need a second course in general chemistry to fulfill a requirement for a variety of majors such as: chemistry, medicine, biology, nursing, dentistry, physical therapy and liberal arts.
3 Natural Science
Prerequisite(s): CHEM 1041 with a grade of C or higher.

- determine the rate law of a reaction using the method of initial rates.
- apply the integrated rate law and half-life equations for zero-order, first-order, and second-order reactions.

Competency 1 (1-6)
03. 01. Demonstrate understanding of scientific theories.
03. 02. Formulate and test hypotheses by performing laboratory, simulation, or field experiments in at least two of the natural science disciplines. One of these experimental components should develop, in greater depth, students’ laboratory experience in the collection of data, its statistical and graphical analysis, and an appreciation of its sources of error and uncertainty. 03. 03. Communicate their experimental findings, analyses, and interpretations both orally and in writing.
