Questions 13-15 refer to the information below. A $$\(0.50 \mathrm{~g}\)$$ sample of $$\(\mathrm{Mg}(s)\)$$ was placed in a solution of $$\(\mathrm{HCl}(\mathrm{aq})\)$$, where it reacted completely. In a third experiment, $$\(0.10 \mathrm{~g}\)$$ samples of $$\(\mathrm{Mg}(\mathrm{s})\)$$ are placed in excess $$\(\mathrm{HCl}(\mathrm{aq})\)$$ of various concentrations: $$\(0.050 \mathrm{M}, 0.10 \mathrm{M}, 0.25 \mathrm{M}\)$$, and $$\(0.50 \mathrm{M}\)$$. The reactions are run in successive order from $$\(0.050 M\)$$ to $$\(0.50 \mathrm{M}\)$$, and the time required for each reaction to go to completion is recorded. As the concentration of $$\(\mathrm{HCl}(\mathrm{aq})\)$$ increases from $$\(0.050 \mathrm{M}\)$$ to $$\(0.50 \mathrm{M}\)$$, which of the following is the expected result?
