Reference: AQA
Following one mixture throughout, by collecting gas in a syringe, recording mass loss on a balance, or tracking colour with a colorimeter, then plotting the measurement against time and taking gradients.
Following a single reaction as it proceeds by recording a physical property that changes with concentration, such as gas volume, mass loss, pH or absorbance.
