Dear year 10 students,
I am posting the syllabus standards and main points of the unit Reaction Test. This will help you prepare well for the coming test. Year 10 IGCSE Chemistry Unit- Reaction rate Standards and Topics for the Unit Test 7.2 Describe and explain the effect of concentration, particle size, catalysts (including enzymes) and temperature on the rate of reactions. Demonstrate knowledge and understanding of a practical method for investigating the rate of a reaction involving gas evolution Learners should use the term rate rather than speed. 7.2(S) Devise and evaluate a suitable method for investigating the effect of a given variable on the rate of a reaction 7.2 Interpret data obtained from experiments concerned with rate of reaction 7.2(S) Describe and explain the effects of temperature and concentration in terms of collisions between reacting particles (An increase in temperature causes an increase in collision rate and more of the colliding molecules have sufficient energy (activation energy) to react whereas an increase in concentration only causes an increase in collision rate.) 7.2 Describe the application of the above factors to the danger of explosive combustion with fine powders, e.g. flour mills, and gases, e.g. methane in mines 6.1 Interpret energy level diagrams showing exothermic and endothermic reactions 6.1(S) Draw and label energy level diagrams for exothermic and endothermic reactions using data provided Describe bond breaking as an endothermic process and bond forming as an exothermic Calculate the energy of a reaction using bond energies 7.2(S) Describe and explain the role of light in photochemical reactions and the effect of light on the rate of these reactions Topics for the week
