Question

In the reaction: 2Na + Cl₂ → 2NaCl, if 2.0 mol of Na and 2.0 mol of Cl₂ are reacted, which is the limiting reagent?
Options
A Na
Correct Answer
B Cl₂
C NaCl
D Both are limiting
Correct Answer

Option A is the correct answer.

Detailed Explanation

The reaction requires 2 mol Na per 1 mol Cl₂. For 2.0 mol Na, only 1.0 mol Cl₂ is needed. Since 2.0 mol Cl₂ is available, Cl₂ is in excess and Na is the limiting reagent.

Hint

Compare the available mole ratio to the required stoichiometric ratio.
