Reaction Stoichiometry

Reaction Stoichiometry. Introduction. Reaction stoichiometry involves the mass relationships between reactants and products in a chemical reaction. It is based on chemical equations similar to the ones studied in the last section.

Enthalpy

Enthalpy. A quick review. Reaction Energies. In our earlier discussions of calorimetry, we used physical sources of heat (hot metal slug). It is also possible to use chemical sources of heat (like hot packs and cold packs).

Calculations Related to Coexistence Curves

Calculations Related to Coexistence Curves. One can imagine putting a volatile liquid in an empty container and seeing one of two results: 1. All of the volatile liquid evaporates . In this case P Gas will be less than the equilibrium vapor pressure of the substance/liquid.

Reaction Mechanism

Reaction Mechanism. The reaction mechanism is the series of elementary steps by which a chemical reaction occurs. The sum of the elementary steps must give the overall balanced equation for the reaction The mechanism must agree with the experimentally determined rate law.
