Consider the following reaction: Cr₂O₃(s)+ 3CCl₄(l)→ 2CrCl₃(s)+ 3COCl₂(g)green colorless purple colorless solid liquid solid gas When the green solid is mixed with the colorless liquid, the mixture starts to bubble and fume. When all action has stopped, a wet purple solid remains. Which substance is the limiting reactant?

Question

Quizplus · Accepted Answer

The limiting reactant is the one that is completely consumed first in a chemical reaction, determining the amount of product formed. In this scenario, the green solid (Cr2O3) reacts with CCl4 to produce CrCl3 and COCl2. Since the reaction stops when the green solid is completely consumed, leaving a purple solid (CrCl3), Cr2O3 is the limiting reactant.
