Course overview
Learners will return after the Easter break to finish off their topics from the previous term and then will move onto their new topic, Rate of Reaction:
Rate of Reaction: This unit focuses on how chemical reactions take place and how concentration, surface area, temperature, pressure (gases only) and adding a catalyst affect the rate of reaction. There are several required practicals in this unit designed to demonstrate how these factors affect rate of reaction. During these practicals, learners will collect data and interpret this to explain how the rate of reaction is changed using collision theory. Learners will construct graphs to interpret and calculate rate of reaction, including calculating gradients and using tangents. They will be introduced to reaction profile diagrams and how these show the activation energy and overall energy change of a chemical reaction and the effect of a catalyst.
Key Concept:
Factors affecting rate of reaction, reaction profiles
Assessment Points:
End of unit assessment will consist of a 40 mark test
Midway assessment set by class teacher which could be an exam question
Guidance:
Learners will receive guidance in a variety of ways. These include marked assessments, reports, feedback in books, 1:1 interaction, Google Classroom.
