Course Outline
Aim
The emphasis of this course will on examination technique as well as the subject matter of the A2 EDEXCEL Specification (9CH01). As many as possible of the below topics will be covered, but the revision will be tailored to the needs and abilities of the group.
Key Topics Covered
- Unit 4
- Kinetics: The rate law, rate constants and reaction orders. Graphical interpretation of experimental results and data. Relationships between mechanisms and the reaction rate determining step. Activation energy. Measurement of reaction rate.
- Entropy:Spontaneity. Calculations of entropy changes for system and surroundings.
- Equilibria: Kp and Kc and related calculations. Gas chromatography. HPLC.
- Acid/base equilibria: Strong and weak acids. Ka and Kw. pH common calculations. Acid/base titrations. Buffer solutions.
- Isomerism.
- Carbonyl compounds: Carboxylic acids. Carboxylic acid derivatives.
- NMR.
- Unit 5
- Aromatic chemistry: Benzene and electrophilic substitution reactions. Phenol.
- Nitrogen compounds: Amines, amides, amino acids and proteins.
- Organic Synthesis.
- Redox titrations involving manganate (VII) and sodium thiosulphate: Quantitative redox and electrode potentials. Use of Eo values in predicting reaction feasibility. fuel cells
- Transition metal chemistry: Copper and Chromium. Chemistry of complexes.
- Thermodynamics: enthalpy, entropy and the feasibility of a reaction. Thermodynamic and kinetic stability, fuel cells.
Other Information
The emphasis of this course will be on examination technique and the consolidation of basic principles and facts.
Past paper questions will be worked through and examiners’ mark schemes and comments provided.
Students attending the course are requested to have scientific calculators with them.
No practical work will be undertaken.
