Rates of reaction
This unit deals with factors affecting rates. Defining terms like rate, order, molecularity rate constant. Extensive discussions are needed to show the affect of temperature on rate of reaction and the use of Maxwell Boltzman distribution curves to predict the increase in rate and to demonstrate the fact that rate of reaction is not proportional to the the number of collisions as all collisions are not effective. Emphasis is also given on the use of catalyst to enhance the rate of a reaction and show how energy barriers can be altered using catalysts......
