Class Objectives
/Class Outline There are various types of chemical reactions, which are kinetically analyzed by suitable methods. Those methods are introduced with experimentally evaluated reaction-rates. The objective in this course is to acquire the following knowledge and ability.
1. Able to understand molecular motions in gases and analyze them.
2. Able to understand molecular motions in liquids and analyze them.
3. Acquire experimental technique to evaluate the reaction rates.
4. Acquire analysis methods using reaction rate equations

Class Schedule Lesson1: Brief review of contents and meanings in this course and introduction of molecular motions in gases (gas pressure and root-mean-square speed)
Lesson2: Kinetic theory of gases: distribution of speeds
Lesson3: Kinetic theory of gases: collisions, transport properties of gaseous molecules
Lesson4: Molecular motion in gases and liquids: effusion rates of gases, molecular movement in liquids
Lesson5: Molecular motions in liquids: conductivities of electrolyte solutions and mobilities of ions
Lesson6: Molecular motions : diffusion
Lesson7: Mid-term examination and summary of molecular motions in gases and liquids.
Lesson8: Chemical reaction rates: experimental technique and reaction rate laws (first-order reactions and half-life time)
Lesson9: Chemical reaction rates: reaction rate laws (second-order reactions, reactions approaching equilibrium)
Lesson10: Chemical reaction rates: temperature dependence (Arrhenius equation)
Lesson11: Chemical reaction rates: interpretation of rate equations (consecutive elementary reactions and steady-state approximations)
Lesson12: Chemical reaction rates: interpretation of rate equations (pre-equilibrium and steady-state approximations)
Lesson13: Examples of reaction mechanisms: Lindemann-Hinshelwood mechanism, photochemistry
Lesson14: Enzyme: Michaelis-Menten mechanism
Lesson15: Final examination and summary of chemical reaction rates

Suggestions on
Preparation and
Review Enough preparation and review of each lesson are necessary because many contents are taught in each lesson.

Requirements

Grading Method The mid-term and final exams are graded out of 100 total points, and a score of 60 or higher is considered a passing grade.

Message "Office hours" are scheduled for Thursdays and Fridays from 17:00 to 18:30; please make active use of them.
This subject is a specialised course intended for Category III students; however, for students assigned to Applied Chemistry programme, it corresponds to the learning and educational objective ‘(Ka) Solid Foundations’.

Other The content of this lecture covers fundamental principles relevant to chemical reactions in general. Consequently, it is important for all programmes within Category III. Particularly for students in Applied Chemistry Programme, it is strongly recommended that they take this course. This is because compulsory subjects such as “Physical Chemistry Exercises” and other compulsory elective subjects cover aspects of reaction kinetics, and the subject is also included in the scope of postgraduate entrance examinations.

Please fill in the class improvement questionnaire which is carried out on all classes.
Instructors will reflect on your feedback and utilize the information for improving their teaching.
