KINETICS revision notes INDEX
Doc Brown's
Chemistry A Level Revision - Notes on the rates of chemical reactions - kinetics
PLEASE NOTE ...
Sections
1. to 4. are for both GCSE, IGCSE, O Level and Advanced Level students (introduction for the latter)
GCSE/IGCSE rates
reaction notes INDEX
Doc Brown's
Chemistry Advanced Level Pre-University Chemistry Revision Study Notes for UK IB
KS5 A/AS GCE advanced level physical theoretical chemistry students US K12 grade 11 grade 12
physical theoretical chemistry courses topics including kinetics rates of
reaction speeds
The
complete index of 'rates' notes
Section 1. General introduction
Why is it
important to know how fast reactions occur?
How can we measure the speed or rate of a chemical reaction?
Experimental
methods are described in this introduction & subsequent sections
Section 2.
Collision theory of
chemical reaction rate factors An introduction to
sections 3a to 3e
Section 3. Factors affecting the speed/rate of a
chemical reaction:
3a
Effect on
rate of
changing reactant concentration in a solution/gas mixture
3b Effect on
rate of
changing pressure in reacting gases (gaseous equivalent of 3a)
3c
Effect on
rate of
changing particle size/surface area & stirring of a solid reactant
3d
Effect on
rate of
changing the temperature of reactants
3e
Effect on
rate of
using a catalyst in a chemical reaction
Activation energy and reaction profiles
Enzymes - biological
catalysts, optimum pH or temperature, use in biotechnology
3f
Light
initiated reactions - effect of changing intensity
Section 4.
Examples of graphs
of rate data, interpretation a summing up of ways your rate data can be
analysed and interpreted at GCSE, IGCSE, O Level and basic ideas for A level
chemistry.
Some ideas to help you with
RISK ASSESSMENT when designing and
performing 'Rates of Reaction' experiments and many other experimental
procedures. Some aspects listed are applicable to 'rates/kinetics' assignments,
others are not applicable at all. Its up to you to decide!
Extra pages for Advanced A Level
Students ONLY
(sections 1. - 4. are for all GCSE and A Level
students etc.)
I am assuming you have already studied
section 1. to 4. because much of this is NOT repeated in the advanced level sections.
Section 5
Maxwell-Boltzmann distribution,
types of catalytic mechanisms, data interpretation, rate
expressions
5.1
The
Maxwell-Boltzmann distribution of molecular kinetic energies (relate
temperature & catalyst factors)
5.2
Heterogeneous
and homogeneous catalysis mechanisms
5.3
Obtaining rate data,
interpreting data, deducing orders of reaction and rate expressions
Section 6
The Arrhenius equation,
calculating activation energy,
6.1
The Arrhenius
equation and calculating the activation energy Ea from kinetics–rates data
6.2
Kinetics versus thermodynamic stability
and reaction feasibility
Section 7. Kinetic case studies
7.1 Hydrolysis of halogenoalkanes
(see also nucleophilic substitution by
water/hydroxide ion)
7.2 Catalysed oxidation of iodide ions by
peroxodisulfate (see also
transition metals - iron)
7.3 Enzyme kinetics
(see also
Enzymes - biological
catalysts, optimum pH or temperature, use in biotechnology)
7.4 The H2/I2/HI equilibrium
(see also chemical
equilibrium)
7.5 Ester hydrolysis
7.6 Acid catalyzed iodination
of propanone (see also organic mechanisms
iodination of ketones)
7.7
Acid – thiosulfate
reaction

understanding of the factors that affect the rate of chemical reaction
have changed methods of storage and cooking of food.
