Chapter 10 Chemical Kinetics II. Composite Mechanisms

Chapter 10 Chemical Kinetics II. Composite Mechanisms. ~Chapter 9 dealt with the more important basic principles of chemical kinetics. To a considerable extent, but not entirely, it dealt with elementary reactions that occur in a single step; the reactant molecules

Chapter 17 Reaction Rates and Equilibrium

Chapter 17 Reaction Rates and Equilibrium. Collision Theory When one substance is mixed with another, the two substances do not react on a macroscopic basis, but react as their individual particles (atoms, molecules, or ions) come together. Collision theory video.

REACTIONS OF ALKYL HALIDES

REACTIONS OF ALKYL HALIDES. Alkyl halides (R-X) undergo two types of reactions : substitution reactions and elimination reactions. In a substitution reaction, the X group in R-X is replaced by a different group, e.g. R-X ?R-OH +X ?

Reaction mechanisms

Reaction mechanisms. Many reactions proceed via a series of steps called a mechanism. A + B → C + D. Fast. C + D → E + F. Slow. E + F → G. Fast. It is highly unlikely that these steps have the same rate. Rate determining step.

The rate-determining step

The rate-determining step. L.O.: What is the rate-determining step of a reaction? What is the connection between the rate equation for a reaction and the mechanism?. Discuss in pairs any of these two situations. Think what are the steps involved and which one is the slowest step.
