A student puts dilute hydrochloric acid at two different temperatures onto two separate lumps of limestone. The limestone lumps each have the same mass. The carbon dioxide gas formed is gathered in a gas syringe. The volume of carbon dioxide collected in 1 minute at each temperature is shown. Which row gives the description and explanation of the results at $50^{\circ}\text{C}$ compared with $25^{\circ}\text{C}$?
- Areaction rate higher; energy of collisions lower
- Breaction rate higher; energy of collisions higher
- Creaction rate lower; energy of collisions lower
- Dreaction rate lower; energy of collisions higher
