Some simple energetics ideas . . .

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

Assorted definitions . . .

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

Hess's Law and simple enthalpy calculations . . .

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.)

Bond enthalpies . . .

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

Lattice enthalpies . . .

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

Enthalpy change of solution . . .

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

Enthalpy change of neutralisation . . .

A brief look at enthalpy change of neutralisation.

Simple measurement of enthalpy changes of reaction . . .

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