  • 2. Assignment brief Unit number and title Unit 1 Chemistry and Our Earth Qualification Level 2 BTEC First Certificate in Applied Science Start date Deadline date Assessor Assignment title Assignment 4 Controlling Industrial Reactions The purpose of this assignment is to: Realise that reaction rates can be altered and manipulated in order to maximise the yield of wanted products, but at times these optimal conditions are compromised for practical and monetary reasons. Scenario As one of the chemists at a local plant, you have been asked to explain to the people operating the chemical plant, the factors which affect rate, yield and atom economy of reactions. Task 1 You will be undertaking a series of four experiments to examine how the rate of a reaction can be altered. Methods for these experiments will be given to you. Complete results tables for the four experiments and draw at least one reaction rate graph. This provides evidence for P5 Task 2 Discover how ammonia is made in industry and in particular how changing the rate of reaction affects this industrial process. This provides evidence for M5 Task 3 Analyse graphs given to you in order to; • determine how different factors affect the yield of an industrial reaction, • use your findings to establish how industry can maximise yield • and optimise atom economy This provides evidence for D3 Sources of information Textbooks Beech J, Milward C and Sochacki F – BTEC Level 2 First Applied Science ActiveTeach CD ROM (Pearson, 2010) ISBN 9781846906114 Brain C, Goodfellow D, Hocking S, Llewellyn R, Kitchin C, Mathews J, Musa 1 and Rhodes P – BTEC Level 2 First Applied Science Student Book (Pearson, 2010) ISBN 9781846906091 Cogill A, Gale P, Hocking S, Llewellyn R, Musa I, Rhodes P, Saunders N and Winterbottom M – BTEC Level 2 First Applied Science Teaching Planning Pack (Pearson, 2010) ISBN 9781846906107 Arnold B (editor) – GCSE Science for Edexcel: Science Student Book (Collins Educational, 2006) ISBN 9780007214488 Bell C, Brodie D, Dawson B and Tiernan A – GCSE Applied Science for Edexcel: Teacher Pack (Folens, 2006) ISBN 9781843039747 Conoley C – Edexcel GCSE Chemistry (Hodder Arnold, 2009) ISBN 9780340914793 Hubbard L – The Essential Chemical Industry (Chemical Industry Education Centre, 1999) ISBN 9781853425776 Hutchings K – Classic Chemistry Experiments (The Royal Society of Chemistry, 2000) ISBN 9780854049196 Nuffield Curriculum Centre – Twenty First Century Science: GCSE Chemistry Textbook (OUP, 2006) ISBN 9780199150502

  • 4. Internal verification of assignment brief Qualification Unit number and title Assessor Internal verifier checklist Comments Are accurate programme details shown? Y/N Are accurate unit details shown? Y/N Are clear deadlines for assessment given? Y/N Is this assignment for whole or part of a unit? Y/N Are assessment criteria to be addressed listed? Y/N Does each task show which criteria are being addressed? Y/N Are these criteria actually addressed by the tasks? Y/N Is it clear what evidence the learner needs to generate? Y/N Are the activities appropriate? Y/N Is there a scenario or vocational context? Y/N Is the language and presentation appropriate? Y/N Is the timescale for the assignment appropriate? Y/N Overall is the assignment fit for purpose? Y/N * If “No” is recorded and the internal verifier recommends remedial action before the brief is issued, the assessor and the internal verifier should confirm that the action has been undertaken Internal verifier Signature Date Action required: Action taken: Assessor Signature Date Internal verifier Signature Date
