ENERGETICS - THERMODYNAMICS NOTES INDEX

Doc Brown's Chemistry Revision Notes

Part 0. Energetics - introduction to energy changes

(4 linked GCSE/IGCSE/O level pages including practical calorimetry methods)

Calorimetry methods and energy transfer calculations from calorimeter results

Parts 1 to 3 are only for Advanced A Level Students

PLEASE note that delta H/S/G values vary slightly from source to source, so I apologise in advance for any inconsistencies that may have arisen as I've researched and developed each section.

Part 1. Basic thermochemistry, calorimetry and enthalpy changes

1.1 Advanced Introduction to enthalpy changes – enthalpies of reaction, formation, combustion

1.2a-1.2b(iii) Thermochemistry – Hess's Law calculations, enthalpies of reaction, combustion, formation etc.

1.2b(iv) Bond Enthalpy Calculations

1.3a–b Experimental methods for determining enthalpy changes and treatment of results

1.4a-b Enthalpy data patterns - combustion of alkanes linear aliphatic alcohols, bond enthalpies and bond Length

1.4c-d Enthalpies of neutralisation, enthalpies of hydrogenation and evidence of aromatic ring structure in benzene

Extra Question page A set of practice enthalpy calculations with worked out answers

Part 2. Extension of defined enthalpies leading to a full exposition of Born-Haber cycle calculations and uses

2.1d–e Enthalpy cycles involving a salt dissolving

2.2a–d The Born–Haber Cycle calculations and uses, comparing theoretical and experimental lattice enthalpies

Part 3. Introducing entropy, feasibility of reactions, entropy and free energy calculations ΔG = ΔH- TΔS

3.1a–g Introduction to Entropy :

3.2 Examples of entropy values and comments, entropy change for change of physical state

3.3a ΔS, entropy change and change of state

3.3b ΔS, Entropy changes and the feasibility of a chemical change

3.5-3.6 Calculating equilibrium constants from ΔG equation, kinetic stability - thermodynamic feasibility
