Quick explanation
Interpret concentration-time graphs
- This point belongs to Rate equations (A-level only), especially Rate equations and orders (A-level only).
- You need to be able to interpret concentration-time graphs.
- The key ideas to know are concentration-time.
- 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 Rate equations and orders (A-level only) to exam-style questions, flashcards, and revision notes for Rate equations (A-level only).
Quick student answer
Which of the following statements about the rate of a reaction is true?
Direct answer
A. The rate of a reaction increases with increasing temperature.
Key terms
- Rate constant (k): A proportionality constant in the rate equation that is specific to a particular reaction at a given temperature.
- Reaction order: The sum of the powers of the concentration terms in the rate equation, indicating the overall dependence of the reaction rate on the concentrations of reactants.
Common trap
Confusing rate constant with rate: Remember that the rate constant is a fixed value for a reaction at a specific temperature, while the rate can change based on the concentrations of reactants.
