Determination of Limiting Reactants or Reagents (VCE SSCE Chemistry): Flashcards

Reactant completely consumed first in a reaction

Reactant remaining after limiting reactant used up

Amount of limiting reactant

Calculate moles of each reactant

Identify which reactant is limiting

Use limiting reactant to find product amount

$n = \frac{m}{M}$

$n = \frac{V}{V_m}$ where $V_m = 24.8$ L mol$^{-1}$

Ensure expensive reactant completely reacts

Compare required vs actual amount using mole ratios
