This document provides instructions for an assignment on chemical reactions for a BTEC Applied Science course. The assignment requires students to: 1) Conduct experiments demonstrating the differences between exothermic and endothermic reactions and factors affecting reaction rates. 2) Explain the concepts of exothermic, endothermic, and reversible reactions as well as how temperature, concentration, and other factors influence reaction rates. 3) For a given industrial reaction (ammonia production), explain how rate is controlled and whether the reaction is exothermic or endothermic.

1. St Ivo Science Centre ID: 22223 Course: BTEC First Certificate/Diploma Applied Science Name: Candidate Number: Tutor Name: Unit: 3 Assignment: 3.3 Start Date: Hand in Date: Assessment Evidence: Your research will help industrial chemists understand the factors involved in chemical reactions This will come from completing the tasks but you may wish to include any extra information that you find. How you present your work is up to you, but you should discuss this with your teacher. Remember to list any websites or books you have used in a bibliography Unit 3 P3 □ M3□ D3 □ P4 □ M4□ D4 □ Grading Criteria Carry out investigations to collect primary data to define what is meant by exothermic and endothermic reactions Using examples of suitable investigations collect primary data and describe the differences between exothermic and endothermic reactions. Explain the processes involved in exothermic and endothermic reactions. Investigate and use primary data to identify the factors affecting reaction rates and reversible reactions. Investigate the use of primary data to describe how factors affect reaction rates and reversible reactions. Use primary data to evaluate how different factors affect reaction rates for a given industrial reaction. Summary Assessor’s Feedback Internal Verifiers Name and Comment Learners Signature
