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

the powerpoint contains notes including:- Transition elements and coloured compounds CHARACTERISTICS of transition metals Why Sc and Zn are not classified as transition elements Electronic configurations of transition metal atoms Electronic config of transition metal Ions Comparing the transition elements with an s-block element Redox reactions of reactions involving transition metal Ligands and complex formation Types of ligands (mono, bi and MULTIDENTATE LIGANDS) Naming complexes Shapes of complexes ORIGIN OF COLOUR of transition metal compounds this powerpoint is very ideal to teachers, students and lectures teaching transition metals in A level.

A powerpoint document which covers Advanced Kinetics (Rate of reactions) chapters from the OCR A Level Chemistry, Cambridge chemistry and edexcel AL Specification. tHIS DOCUMENT IS GOOD FOR LEARNERS AND TEACHERS teaching the above systems. OBJECTIVES COVERED 1 explain and use the terms rate equation, order of reaction, overall order of reaction, rate constant, half-life, rate-determining step and intermediate 2 (a) understand and use rate equations of the form rate = k [A]m[B]n (for which m and n are 0, 1 or 2) (b) deduce the order of a reaction from concentration-time graphs or from experimental data relating to the initial rates method and half-life method © interpret experimental data in graphical form, including concentration-time and rate-concentration graphs (d) calculate an initial rate using concentration data (e) construct a rate equation 3 (a) show understanding that the half-life of a first-order reaction is independent of concentration (b) use the half-life of a first-order reaction in calculations 4 calculate the numerical value of a rate constant, for example by: (a) using the initial rates and the rate equation (b) using the half-life, t1/2, and the equation k = 0.693/t1/2 5 for a multi-step reaction: (a) suggest a reaction mechanism that is consistent with the rate equation and the equation for the overall reaction (b) predict the order that would result from a given reaction mechanism and rate-determining step © deduce a rate equation using a given reaction mechanism and rate-determining step for a given reaction (d) SN1 AND SN2 MECHANISMS
