About Stoichiometry

Stoichiometry is the study of the quantitative relationships between reactants and products in chemical reactions.

Key Concepts:

  • Limiting Reactant: The reactant that is completely consumed in a reaction, limiting the amount of product formed
  • Theoretical Yield: The maximum amount of product that can be produced based on the limiting reactant
  • Excess Reactants: Reactants that remain after the reaction is complete
  • Mole Ratios: The ratios of coefficients in a balanced chemical equation

Applications:

  • Chemical manufacturing and process optimization
  • Laboratory experiment planning
  • Cost analysis in chemical production
  • Environmental impact assessments
  • Quality control in chemical industries
  • Research and development in chemistry
