1
Chemical kinetics: Introduction : The branch of physical chemistry which deal with the study of rate of reaction, mechanisam of reaction,and various factors which affect the rate of reaction.
2
Reaction rate : Concept : The stopped-flow technique and its use in studying chemical reactions is described. The speed or rate of a reaction is discussed.
3
Expiriment : Concentration vs time plots are recorded for reactants and product in a chemical reaction. Characteristic features for rates of change in the concentrations of reactants and product are explored.
4
Rate of reaction : Concept: The relationships between the relative rates of change in concentration of reactants and products is discussed. The general expression for the rate of reaction is presented.
5
Expiriment : The stoichiometric coefficients for a chemical equation are determined by comparing the slopes of concentration-time plots for the reactants and products.
6
Defferential rate law : Concept : Differential rate laws for zero-, first-, and second-order reactions are described and explained.
7
Experiment : The differential rate law and the rate constant are determined for a reaction by examining how the rate of reaction varies with the reactant concentration
8
Integrated rate laws : Concept : Integrated rate laws for zero-, first-, and second-order reactions are described and explained.
9
Experiment : The rate law and the rate constant are determined for a reaction by preparing characteristic kinetics plots from concentration-time data.
10
Half life : Concept : The half-life of a reaction is defined and explained.
11
Experiment : The half-life is measured for various initial concentrations for zero-, first-, and second- order reactions. The data is analyzed graphically to determine the relationship between the half-life and reactant concentration for each order reaction and to determine the rate constant for each reaction.
12
Method of initial rates : Concept : The determination of a rate law by the Method of Initial Rates is described.
13
Experiment : The rate law and rate constant for a reaction is determined using the Method of Initial Rates.
14
Isolaition method : Content: The determination of a rate law by the Isolation Method is described Experiment : The rate law and rate constant for a reaction is determined using the Isolation Method.
15
Concept :The reaction between bromate ion and bromide ion in acidic aqueous solution is described. Kinetics of the Bromate-Bromide Ion ReactionKinetics of the Bromate-Bromide Ion Reaction :
16
Experiment : The rate law and rate constant for the bromate-bromide ion reaction is determined. A selection of solutions and a stopped-flow apparatus are available. Students must devise their own experimental strategy for determining the rate law and the rate constant.
