An investigation method for finding the rate of reaction of calcium carbonate with dilute hydrochloric acid under different conditions is shown. • Pour $50\text{ cm}^3$ of dilute hydrochloric acid into a conical flask. • Add a measured volume of water to the conical flask. • Warm the conical flask to the necessary temperature. • Put $1.0\text{ g}$ of calcium carbonate into the conical flask. • Record the time needed for the reaction to end. Which volume of water and which temperature results in the shortest time for the reaction to complete?
- A10 $\text{cm}^3$, $30\degree\text{C}$
- B10 $\text{cm}^3$, $50\degree\text{C}$
- C40 $\text{cm}^3$, $30\degree\text{C}$
- D40 $\text{cm}^3$, $50\degree\text{C}$
