1. How is the graph of mass loss against time related to the rate of the reaction between calcium carbonate and hydrochloric acid?
(The graph shows that when the molecular is smaller in size the reaction rate tends to be faster at the beginning however the same at the end.)
2. How does decreasing the particle size of calcium carbonate affect the reaction?
3. Suggest another experimental arrangement that could be used to monitor the rate of reaction.
(thanks)

1) the graph will be a curve and the gradient f the curve is related to the speed of reaction. the steeper the gradient, the faster the reaction..
2) it will speed up the reaction because there is a larger surface area of calcium carbonate for hydrochloric acid to act on.
3)connect a syringe to the mouth of the conical flask, making sure that no air can escape. carbon dioxide gas will be produced and readings on the syringe can be taken
