"Kinetics"

Revision

• Chemical kinetics
• Reaction rate
• Rate equation
• Elementary reaction
• Reaction rate constant
• Rate-determining step
• Activation energy
• Arrhenius equation

Multi-step reactions

• Steady state approximation

Unimolecular reactions

• Lindemann mechanism

A + M → A* + M

A* + M → A + M

A* → products

Bimolecular reactions

• Collision theory (rubbish)
• Transition state theory
• Molecularity?

Reactions in solution

• Diffusion-controlled reactions
• Activation-controlled reactions

Applications

• Enzyme catalysis, Michaelis–Menten kinetics
• Oscillating chemical reactions, e.g. Briggs–Rauscher reaction, Belousov–Zhabotinsky reaction
