Chemical Energetics Menu

Deals with the basic ideas about energy changes during chemical reactions, including simple energy diagrams and the terms exothermic and endothermic.

Explains what enthalpy changes are and gives definitions of the key terms: standard enthalpy changes of reaction, formation and combustion.

States and explains Hess's Law and how it is used. A brief introduction to enthalpy change calculations. (Full explanations of these are given in my calculations book, and I can't repeat them in detail here. That applies to the next links as well.)

Explains what bond enthalpies are, and gives a brief introduction to their use in calculations.

An explanation of lattice enthalpies, how they can be used in Born-Haber cycles, and the factors which affect them.

The relationship between enthalpies of solution, lattice enthalpies and hydration enthalpies.

A brief look at enthalpy change of neutralisation.

A brief introduction limited, I'm afraid, by the need to protect sales of my calculation book.
