An excess amount of calcium carbonate is allowed to react with dilute hydrochloric acid. At fixed time intervals, the volume of carbon dioxide formed is recorded. The findings are given for experiment 1. The experiment is then carried out again, with just one alteration to the reaction conditions. The findings for experiment 2 are shown. What alteration has been made in experiment 2?
- AThe concentration of the acid is increased.
- BThe volume of acid is increased.
- CThe mass of calcium carbonate is increased.
- DThe calcium carbonate is powdered.
