Given:

An experimental set-up where there are four test tubes containing different concentrations of hydrochloric acid, all at 25 degrees Celcius. All test tubes were added with 1 gram of Zn cube (at the same time).

The reaction which occurs at the fastest rate is the test tube where HCl concentration is greatest. The high concentration of HCl enhances the speed of the reaction.
