In two separate experiments, hydrochloric acid is placed with excess calcium carbonate. The hydrochloric acid has two different concentrations, while the temperature is identical in both experiments. A graph displays the volume of carbon dioxide gas released against time. Which row is correct?
- Acollision rate higher, collision energy no change
- Bcollision rate higher, collision energy higher
- Ccollision rate lower, collision energy no change
- Dcollision rate lower, collision energy higher
