An experiment is done to determine the reaction rate between hydrochloric acid and zinc. $\text{Zn(s)} + 2\text{HCl(aq)} \rightarrow \text{ZnCl}_2\text{(aq)} + \text{H}_2\text{(g)}$ The experiment results are shown. What label is used for the y-axis?
- Aamount of $\text{ZnCl}_2$ produced
- Bconcentration of $\text{HCl}$
- Cmass of $\text{Zn}$ reacted
- Dvolume of $\text{H}_2$ produced
