Quick explanation
Measure reaction rates using appropriate methods
- This point belongs to AS practical skills and required practical activities, especially AS apparatus and techniques.
- You need to be able to measure reaction rates using appropriate methods.
- The key ideas to know are appropriate, rates, and reaction.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
Key concepts
Why it matters
This objective helps connect AS apparatus and techniques to exam-style questions, flashcards, and revision notes for AS practical skills and required practical activities.
Quick student answer
Which of the following methods can be used to measure the rate of a reaction involving a gas?
Direct answer
A) Measuring the change in mass
Key terms
- Rate of reaction: The speed at which reactants are converted into products, typically measured in mol/dm³/s.
- Catalyst: A substance that increases the rate of a chemical reaction without being consumed in the process.
Common trap
Confusing rate with rate constant: Remember that the rate of reaction depends on the concentration of reactants and can change over time, while the rate constant is specific to a particular reaction at a given temperature.
