3 cards from this section. Quick, good the night before a test.
What is a limiting reactant?
Think about what happens first in a reaction.
Why is it important to identify the limiting reactant?
Consider what dictates how much product you will have.
What is a limiting reactant?
Think about which reactant is the constraint in the reaction.
True or False: Theoretical yield can be higher than the actual yield.
Consider why actual production never meets theoretical calculations.
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.
Calculate using mole ratios from the balanced equation.
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.
Use stoichiometry from the balanced reaction to find yields.
