## Learning Outcomes

By the end of the course, the student must be able to:

• Express differential rate laws for elementary and composite chemical reactions.
• Derive and apply integral rate laws for the most common elementary and composite reactions.
• Apply correctly the steady-state approximation for the rate constant.
• Derive and apply the rate law for the Michaelis-Menten mechanism of enzymatic catalysis.
• Compute the thermodynamic properties of a gas from the kinetic theory.
• Compute the rate constants of unimolecular and bimolecular reactions from the collision theory.
• Apply the transition state theory to derive a general expression for the rate constant.
• Use the transition state theory to compute rate constants of elementary reactions.
