Identify limiting reactants
Free printable Chemistry science worksheet for "Identify limiting reactants" — practice moles and stoichiometry. No-prep, print or assign online.
High school students identify limiting reactants in chemical reactions by analyzing mole ratios and determining which reagent is consumed first in this stoichiometry worksheet. Teachers can use it during a moles and stoichiometry unit to push students from balanced equations to quantitative reasoning about reaction efficiency. The concept is central to chemistry lab work, industrial processes, and understanding why reactions rarely go to theoretical completion.
Learning objectives
- Identify the limiting reactant in a chemical reaction using mole ratio analysis
- Calculate the amount of product formed based on the limiting reactant
- Determine the excess reactant remaining after the reaction goes to completion
