Question
**Question:**

Identify the principal factor for the rate of disappearance of magnesium metal when added to 1.0 M HCl, 3.0 M HCl, and 6.0 M HCl solutions respectively. In which solution will the reaction rate be the greatest?

**Options:**

- 10.0 M
- 12.0 M
- 3.0 M
- 6.0 M

**Analysis:**

This question highlights the relationship between the concentration of hydrochloric acid (HCl) and the rate of reaction with magnesium metal. The principal factor in this context is the concentration of HCl. Generally, higher concentrations of reactants lead to higher reaction rates due to more frequent and effective collisions between particles. Therefore, the reaction rate is likely to be greatest in the solution with the highest concentration of HCl, which is 6.0 M based on the question's initial setup. 

The options provided include concentrations beyond the given setups, suggesting a focus on understanding that reaction rates typically increase with concentration. Thus, the correct choice is likely to be the highest concentration listed in the options provided.
