GCSE Chemistry Revision "Limiting reactant"
Freesciencelessons・4 minutes read
The limiting reactant in a chemical reaction determines the amount of product that will be produced, while the excess reactant remains unused. Calculating the mass of the product involves multiplying the number of moles by the relative formula mass.
Insights
- The limiting reactant in a chemical reaction is crucial as it determines the amount of product that will be formed, while the excess reactant remains unreacted.
- To calculate the mass of the product in a reaction, one needs to consider the number of moles and the relative formula mass, with the limiting reactant playing a significant role in this calculation.

Limiting Reactant Determines Product Yield
- In chemical reactions, reactants are the starting materials, while products are what is produced. The reactant that is fully used up is called the limiting reactant, while the one not used up is the excess reactant.
- The amount of product in a reaction is determined by the limiting reactant. Using more of one reactant ensures that all of it fully reacts, while the excess reactant remains after the reaction.
- Calculating the mass of the product involves multiplying the number of moles by the relative formula mass. The limiting reactant dictates the amount of product produced in a reaction.
