Show transcript
Measuring volume of gas produced throughout a reaction allows the changing rate of reaction to be calculated.
Errors in measuring volumes of gas over time include timing, reading volumes in real time and gas displaced by the bung.
Measuring an end-point in a reaction allows direct and simple comparison of reaction rates.
Errors in measuring end-points include subjectivity of observations, measuring times and volumes, and contamination.
