Two experiments are carried out to study the rate of reaction between calcium carbonate and dilute hydrochloric acid.
Experiment 1: 5 g of large chips of CaCO₃ with 50 cm³ of 1.0 mol/dm³ HCl.
Experiment 2: 5 g of powdered CaCO₃ with 50 cm³ of 1.0 mol/dm³ HCl.
Which statement compares the volume of CO₂ produced and the rate of reaction?
Experiment 1: 5 g of large chips of CaCO₃ with 50 cm³ of 1.0 mol/dm³ HCl.
Experiment 2: 5 g of powdered CaCO₃ with 50 cm³ of 1.0 mol/dm³ HCl.
Which statement compares the volume of CO₂ produced and the rate of reaction?
- Experiment 1 gives a larger final volume of CO₂ and a faster rate.
- Experiment 1 gives the same final volume of CO₂ but a faster rate.
- Experiment 2 gives a larger final volume of CO₂ but a slower rate.
- Experiment 2 gives the same final volume of CO₂ but a faster rate.
