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.

These are a powerpoint presentation on chemistry A level notes on entropy. The notes have been well written to help students and teachers undertaking chemistry a levels in edexcel IB and cambridge based syllabuses. What is Entropy Comparing entropy values Predicting entropy change Predicting sign of entropy Calculating entropy change of a reaction Spontaneous and non-spontaneous reaction Calculating the entropy change of the system Calculating the entropy change of the surroundings Calculating total entropy change ROLE OF TEMPERATURE Why water freeze at -5 but does not at -5 More Entropy changes Dissolving substances in water SOLUBILITY OF GROUP 2 SULPHATES AND HYDROXIDES Lattice energy and born Haber cycles lattice energy construct Born–Haber cycles enthalpy change of atomisation and electron aff inity eff ect of ionic charge and ionic radius on the numerical magnitude of a lattice energy ■■ interpret and explain qualitatively the trend in the thermal stability of the nitrates and carbonates of Group 2 elements in terms of the charge density of the cation and the polarisability of the large anion. apply Hess’s law to construct energy cycles to determine enthalpy changes of solution and enthalpy changes of hydration. ■■ interpret and explain qualitatively the variation in solubility of Group 2 sulfates in terms of the relative values of the enthalpy change of hydration and the corresponding lattice energy.

This is a powerpoint display notes meant for Cambridge, Edexcel and IB chemistry teachers and students. The se are notes that I use to teach in my class. They ahve been well prepared using the three core books. The notes include; Brønsted– Lowry theory of acids and bases diff erences in behaviour between strong and weak acids and bases and the pH values of their aqueous solutions in terms of the extent of dissociation. AMPHOTERIC AND AMPHIPROTIC Conjugate acids and conjugate bases NITRIC ACID AS A BASE terms pH, pKa and Kw and use them in calculations [H+(aq)] and pH values for strong and weak acids and strong bases choice of suitable indicators for acid–base titrations changes in pH during acid–base titrations and explain these changes in terms of the strengths of the acids and bases calculate Ksp from concentrations and vice versa common ion eff ect term partition coeff icient partition coeff icient for a system in which the solute is in the same molecular state in the two solvents. PH CURVES AND INDICATORS How a buffer solution works Making a Buffer solution How to make a buffer Calculating the pH of a buffer solution Uses of Buffers welcome

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

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
