CHEM 225 Physical Chemistry for Biosciences

School of University Arts and Sciences

CHEM 225 Physical Chemistry for Biosciences presents the basic concepts of chemical thermodynamics and kinetics that apply to biological systems. Students will explore why gases would behave differently at different conditions (e.g. deep sea diving, high altitude, other planets), how ideal engines function, why some reactions spontaneous, how do we explain the effect of salting roads in winter, how batteries and our metabolism generate energy, how kinetics is related to thermodynamics (why diamonds do not break down into graphene) and how we use of spectroscopy to explore biological structures. In the laboratory, quantitative properties of systems are measured, to illustrate the theory discussed in lectures.

Prerequisites: CHEM 125 and MATH 101 both with a minimum grade of 60%

Learning Outcomes

Upon successful completion of this course, the learner will be able to:

  1. Predict how gases behave under different conditions
  2. Track the flow of heat during biological processes, and understand the basic laws of thermodynamics
  3. Assess realistic problems using both thermodynamics and kinetics
  4. Interpret structure of simple biological molecules using spectroscopy
  5. Assess the effect of temperature on reaction rates, apply transition state theory and be able to combine rate laws for chemical reactions
  6. Connect concepts in lectures with experiments performed in physical chemistry lab
  7. Quantify the effect of catalysis and enzymes in our daily life
  8. Exhibit respect for colleagues, punctuality, willingness to think independently, and pride in presentation of work

Teaching and Learning Approach

The lectures in this course focus on the introduction of concepts and connecting concepts to real world situations. Students will be encouraged to use problem-solving strategies developed in previous courses to new situations. Students are encouraged to participate in class via in-class assignments. The lab provides opportunities to develop hands-on skills and to reinforce the concepts introduced in lectures.
