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