Physical Chemistry 3


Physical Chemistry 3 will deal with reaction kinetics and reactor design for homogeneous reactions. Students will learn about rates of reaction, stoichiometry and order, different types of reactions, and the effect of temperature on reaction rates as well corresponding reaction mechanisms. Practical applications on reactor design based on reaction kinetics would also be discussed.

Learning outcomes

At the end of this course, students should be able to:

  • Discuss concepts in reaction kinetics qualitatively
  • Derive and solve rate equations specific to chemical reactions
  • Carry out calculations for reactions with several mechanism steps
  • Choose and use appropriate methods to determine reaction rates from experimental data
  • Determine which reactor would be best suited for a specific reaction based on their kinetics
