Course description

The fundamentals of Physical Chemistry are studied with emphasis upon the application of these on pharmaceutical sciences. The main elements that are covered in this course are: Thermodynamics, Kinetics and electrochemistry.

 

Prerequesites

General and Organic Chemistry and working knowledge with differential calculus.

Calculus II, differential equations I (MAT 100 and MAT610, respectively) are highly recommended.

 

Grading

Grades will be based on a midterm exam (40 % of the final grade) and a 2.5-hour final exam (60% of the final grade), which will include new cumulative material. Exams will require calculation, and derivation/manipulations, similar to problems and exercises given in the text. No test grades will be dropped. The grading scale will be determined at the end of the course and may not follow a linear scale.

 

No make-up exams will be given for the midterm exam. If the midterm exam is missed, the final grade will be calculated from the average of the quizzes and the final exam. If the final exam is missed, a grade of Incomplete will be submitted to the registrar and a makeup final will be given at a time and day determined by the instructor. The material for the exams will be extracted from the assigned text books, lectures and other handouts/scientific articles.
