Question 1

What is a limiting reactant?

  • The reactant that creates the most product
  • The first reactant used in the reaction
  • The reactant that runs out first

💡 Hint: Think about which reactant is the constraint in the reaction.

Question 2

True or False: Theoretical yield can be higher than the actual yield.

  • True
  • False

💡 Hint: Consider why actual production never meets theoretical calculations.

Challenge Problems

Push your limits with challenges.

Question 1

In a chemical reaction 2A + 3B → 4C, you have 8 moles of A and 12 moles of B. Determine the limiting reactant and maximum moles of C produced.

💡 Hint: Calculate using mole ratios from the balanced equation.

Question 2

Sodium bicarbonate and acetic acid in reaction: NaHCO₃ + CH₃COOH → CO₂ + NaCH₃COO + H₂O uses 1 mole NaHCO₃ and 1 mole CH₃COOH. If you start with 0.5 moles of NaHCO₃ and 0.8 moles of CH₃COOH, find the limiting reactant and how much CO₂ can be produced.

💡 Hint: Use stoichiometry from the balanced reaction to find yields.
