In these notes it summarises what the collision theory is and what the role of a catalyst is. Also describes what the Boltzmann distribution is and the use of le chateliers principle as well as calculating the equilibrium constant.

Here there are 3 components that will be summarised: One is about group 2 elements which will explain the redox reactions and reactivity of these elements Then there is the characteristic physical properties of halogens and their reactions and finally there’ll be a summary to the different tests for ions.

In these notes it summarises what enthalpy of formation, combustion, neutralisation and reactions are. Also learn how to calculate bond enthalpies and how to construct Hess’ law cycles.

These are notes that summarise the structure of the periodic table and the trends in electron configuration and ionisation energy . It also summarises periodic trends in structure and melting points.

Handwritten, detailed notes with diagrams covering all aspects of this module.

For students doing A Level Chemistry under the OCR A specification. This module is for AS Level too. The main themes in this summary guide include: The periodic table and periodicity; Group 2 and the halogens; Qualitative analysis; Enthalpy changes; Reaction rates and equilibrium (qualitative). The chapters are condensed into concise snippets, less than A4 page, for effective revision.
