- AAdding $10\,\text{cm}^3$ of water to the $50\,\text{cm}^3$ of acid increases the rate of the reaction.
- BIncreasing the size of the pieces of calcium carbonate increases the rate of the reaction.
- CIncreasing the temperature increases the rate of the reaction.
- DThe mass of the conical flask and its contents increases as carbon dioxide is formed.
