Rate laws and integrated rate equations
Find the order of a reaction from concentration–time graphs, initial rates or a clock reaction.
Open the interactive simulation →How to use this simulation
- Choose an experiment: integrated rate laws, initial rates, pseudo-first order or the thiosulfate clock.
- For a mystery reaction, press play and see which of the three plots is a straight line.
- For initial rates, compare experiments where only one concentration changes.
- Enter your answer and check it.
What to notice
- Zero order: [A] is straight. First order: ln[A] is straight. Second order: 1/[A] is straight.
- If doubling [A] doubles the rate, the order in A is 1.
