CHAPTER 9: Rate of  Reaction

• Rate of Reaction
• Factors Affecting Rate of Reaction
• Catalysis

Learning outcomes:

• explain and use the terms: rate of reaction, activation energy and catalysis
• explain qualitatively, in terms of collisions, the effect of concentration changes on the rate of a reaction
• show understanding, including reference to the Boltzmann distribution, of what is meant by the term activation energy
• explain qualitatively, in terms both of the Boltzmann distribution and of collision frequency, the effect of temperature change on the rate of a reaction 
• (i) explain that, in the presence of a catalyst, a reaction has a different mechanism, i.e. one of lower activation 

(ii)  interpret this catalytic effect in terms of the Boltzmann distribution.

• describe enzymes as biological catalysts (proteins) which may have specific activity
