1) The apparatus below can be used to measure the rate of reaction when a gas is produced.
a) Describe how the above apparatus can be used to draw a rate of reaction graph.
b) If there is a greater rate of reaction, will the mass be lost quicker or more slowly?
c) The rate of reaction graph for this experiment is shown below.
b) If there is a greater rate of reaction, will the mass be lost quicker or more slowly?
c) The rate of reaction graph for this experiment is shown below.
i) When are reactions taking place; the curved part or the flat part?
ii) When have the reactions stopped; the curved part or the flat part?
2) The apparatus below can be used to measure the rate of reaction when a precipitate is formed.
