- (a) The roles of
has to be explained.
- (b) Why the fluorine radical is not important in this mechanism has to be explained.
- (c) One suggestion to reduce the concentration of chlorine radicals is to add hydrocarbons such as ethane to the stratosphere. How this will work has to be explained.
- (d) Potential energy versus reaction progress diagrams for the uncatalyzed and catalyzed destruction of ozone has to be drawn.
Rate of a reaction: It represents the speed at which a chemical reaction runs. How much concentration of reactants consumed and how much concentration of product formed in a unit of time is said to be rate of reaction.
- Rate of reaction depends on time, temperature, pressure, concentration, and
of the reaction.
