Reactions and Stoichiometry

Class 2 reviews chemical reactions and their stoichiometry. Relationships between stoichiometry and chemical composition, heats of reaction, and associated concepts are presented.

Learning Outcomes

After completing Class 2 you should…

  • Know
    • the definition of an elementary reaction, reactive intermediate, balanced reaction, stoichiometric coefficient, mathematically independent reaction or equation, heat of reaction, exothermic and endothermic reaction, equilibrium, reversible and irreversible reaction, limiting reactant, and parallel, series, and series-parallel reaction networks
    • the defining equations for true and apparent extent of reaction, stoichiometric coefficient matrix, heat of reaction at 298 K, heat of reaction at any temperature, conversion, limiting reactant, overall yield, and overall selectivity
  • Understand
    • in Reaction Engineering Basics, the stoichiometric coefficients of reactants are negative and those of products are positive
    • the number of mathematically independent reactions equals the rank of the stoichiometric coefficient matrix
  • Be able to
    • identify a set of mathematically independent reactions/equations
    • identify limiting reactants
    • write and use equations inter-relating initial composition, current composition, stoichiometry, and reaction progress
    • calculate heat of reaction as a function of temperature

Prepare

  • Read Chapter 2 of REB, The Book
  • Watch the Class 2 Preparation Video
