Table 3 suggests that at a concentration of 1.5M H2SO4, there was an increase in the volume of hydrogen gas and the reaction rate. This increase in volume cannot solely be attributed to the concentration of H2SO4 as the mass of magnesium was controlled to reduce volume, resulting in a greater volume. Compared to 1.5M H2SO4, there was a difference of 28mL in the volume of hydrogen gas produced when using 0.1M H2SO4. This increase is attributed to a higher availability of hydrogen ions in the solution. The overall graph shows a positive correlation between the concentration of sulfuric acid and the volume of hydrogen gas produced. This correlation was found to be linear in nature, which aligns with the hypothesis that a higher concentration of sulfuric acid would lead to an increase in the volume of H2.
The general trend of the graph indicates that a higher concentration of sulfuric acid leads to a faster reaction rate. Similar to the relationship between the concentration of sulfuric acid and the volume of hydrogen gas, the relationship is linear. This suggests that as the concentration of sulfuric acid increases, the rate of reaction also increases due to the collision theory in chemical kinetics. At a higher concentration of sulfuric acid, magnesium has a higher chance of collision, which is why it leads to a greater reaction rate.
