AS Biology unit 1 topic 1 notes for students taking A level biology. These notes are well structured with clear images to guide the student on what the notes are talking about.
The notes covers Cell physiology, Cytology and microscopy.
Cambridge AS LEVEL CHEMISTRY NOTES TOPIC 1. These notes are written for teachers teaching and students undertaking AS LEVEL CHEMISTRY FOR CAMBRIDGE SYLLABUS.
THEY COVER TOPIC 1 OF AS CHEMISTRY. MOLES
these are comprehensive notes showing what students should know if sitting for AS level exams. AS Biology notes are written by me being an experienced teacher in the same.
The notes cover topic on enzymes:
Summary
Chemical energetics powerpoint ppt notes for A Level chemistry. These anotes are suitable for teachers teaching both IAL Cambridge and IAL Edexcel.
They are also suitable for learners since they have been created and summarised to suit both teaching and revision
This Powerpoint material is suitable for students and teachers sitting and teaching chemistry in A LEVELS for all syllabuses.
The following are areas covered in this document.
1 explain that catalysts can be homogeneous or heterogeneous
2 describe the mode of action of a heterogeneous catalyst to include adsorption of reactants, bond weakening
and desorption of products, for example:
(a) iron in the Haber process
(b) palladium, platinum and rhodium in the catalytic removal of oxides of nitrogen from the exhaust gases
of car engines
3 describe the mode of action of a homogeneous catalyst by being used in one step and reformed in a later
step, for example:
(a) atmospheric oxides of nitrogen in the oxidation of atmospheric sulfur dioxide
(b) Fe2+ or Fe3+ in the I–/S2O8 2– reaction
4 understand that knowledge of the rate equations for the hydrolysis of
halogenoalkanes can be used to provide evidence for SN1 and SN2 mechanisms for tertiary and primary halogenoalkane hydrolysis
5 be able to use calculations and graphical methods to find the activation energy for a reaction from experimental data
The Arrhenius equation will be given if needed.
6 understand the use of a solid (heterogeneous) catalyst for industrial reactions, inthe gas phase, in terms of providing a surface for the reaction
