In chemical reactions, usually one chemical gets used up before the other. The chemical used up first is the limiting reactant. Once the limiting reactant is used up the reaction is stopped.
- Limitng reactant determines the quantity of products formed
- to find the L.R. assume one reactant is used up. Determine how much of this reactant is required.
Example :
2 H2 + O2 --> 2 H2O
8 mol x 2 = 16 mol
1
Hydrogen = limiting factors
please watch this video for more examples of limiting reactants.. thanks :)
