Limiting reactant

• Limiting reactant


  The reactant that is fully used up in a chemical reaction
• Excess reactant


  The reactant that is not fully used up in a chemical reaction
• Effect of limiting reactant

  1. Determines the amount of product formed

  2. If limiting reactant is used up, no more product can be formed
• Calculating mass of product: Mass = Number of moles x Relative formula mass
