2. Thermochemical equation - Wikipedia

   en.wikipedia.org/wiki/Thermochemical_equation

   In thermochemistry, a thermochemical equation is a balanced chemical equation that represents the energy changes from a system to its surroundings. One such equation involves the enthalpy change, which is denoted with Δ H {\displaystyle \Delta H} In variable form, a thermochemical equation would appear similar to the following:

3. Thermochemistry - Wikipedia

   en.wikipedia.org/wiki/Thermochemistry

   Thermochemistry rests on two generalizations. Stated in modern terms, they are as follows: [1] Lavoisier and Laplace's law (1780): The energy change accompanying any transformation is equal and opposite to energy change accompanying the reverse process.

4. Standard enthalpy of reaction - Wikipedia

   en.wikipedia.org/wiki/Standard_enthalpy_of_reaction

   Most values of standard thermochemical data are tabulated at either (25°C, 1 bar) or (25°C, 1 atm). [ 2 ] For ions in aqueous solution, the standard state is often chosen such that the aqueous H + ion at a concentration of exactly 1 mole/liter has a standard enthalpy of formation equal to zero, which makes possible the tabulation of standard ...

5. Stoichiometry - Wikipedia

   en.wikipedia.org/wiki/Stoichiometry

   Gas stoichiometry is the quantitative relationship (ratio) between reactants and products in a chemical reaction with reactions that produce gases. Gas stoichiometry applies when the gases produced are assumed to be ideal, and the temperature, pressure, and volume of the gases are all known. The ideal gas law is used for these calculations.

6. Reaction mechanism - Wikipedia

   en.wikipedia.org/wiki/Reaction_mechanism

   In chemistry, a reaction mechanism is the step by step sequence of elementary reactions by which overall chemical reaction occurs. [1]A chemical mechanism is a theoretical conjecture that tries to describe in detail what takes place at each stage of an overall chemical reaction.

9. Standard enthalpy of formation - Wikipedia

   en.wikipedia.org/wiki/Standard_enthalpy_of_formation

   For many substances, the formation reaction may be considered as the sum of a number of simpler reactions, either real or fictitious. The enthalpy of reaction can then be analyzed by applying Hess' law, which states that the sum of the enthalpy changes for a number of individual reaction steps equals the enthalpy change of the overall reaction.
