The rate of reaction between calcium carbonate and dilute hydrochloric acid is determined in three separate experiments. In experiment 1, the calcium carbonate is powdered, and an excess of hydrochloric acid is used. In experiment 2, the calcium carbonate is in lumps, and an excess of hydrochloric acid is used. In experiment 3, the calcium carbonate is in lumps, less hydrochloric acid is used, and the calcium carbonate is in excess. The outcomes of these experiments are shown. Which statement is correct?
- AExperiment 1 is shown by curve X.
- BExperiment 1 is shown by curve Y.
- CExperiment 2 is shown by curve Y.
- DExperiment 3 is shown by curve Z.
