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 Born-Haber 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.
