The equation for the reaction of magnesium with hydrochloric acid is shown. $\text{Mg} + 2\text{HCl} \rightarrow \text{MgCl}_2 + \text{H}_2$ The rate of this reaction is investigated with the apparatus shown. Which change would increase the rate of reaction?
- Alowering the temperature of the acid
- Busing a larger volume of the same hydrochloric acid
- Cusing less concentrated hydrochloric acid
- Dusing the same mass of magnesium powder
