The graph presents the outcomes of two experiments that investigate the rate of reaction between excess calcium carbonate and dilute hydrochloric acid. In each experiment, the volume of carbon dioxide released is recorded at fixed time intervals. Which statement describes the difference in conditions between experiments 1 and 2?
- AIn experiment 2 a higher concentration of dilute hydrochloric acid is used.
- BIn experiment 2 a higher temperature is used.
- CIn experiment 2 the mass of calcium carbonate is greater.
- DIn experiment 2 the particle size of calcium carbonate is greater.
