Rate of reactions written questions
Practise G3 Pure / O-Level Chemistry rates, experiment comparisons and collision explanations through marked written questions.
Learning goals
- Describe how concentration, pressure, particle size and temperature affect reaction rate, and explain each effect using collisions between particles
- Define a catalyst and describe how catalysts, including enzymes, affect reaction rate
- Explain how a pathway with lower activation energy increases reaction rate
- State that some compounds act as catalysts in industrial processes and that enzymes are biological catalysts
- Suggest a method to investigate how a given variable affects reaction rate
- Interpret data from rate of reaction experiments
