A sample of calcium carbonate is made to react with dilute hydrochloric acid, giving a final gas volume of $60\,\text{cm}^3$. The reaction ends after $120\,\text{s}$. The experiment is then carried out again at a lower temperature, while every other condition remains unchanged. Which row gives the outcomes for the second experiment?
- Afinal volume: $40\,\text{cm}^3$; time: $120\,\text{s}$
- Bfinal volume: $40\,\text{cm}^3$; time: $160\,\text{s}$
- Cfinal volume: $60\,\text{cm}^3$; time: $120\,\text{s}$
- Dfinal volume: $60\,\text{cm}^3$; time: $160\,\text{s}$
