PREFACE to Physical Chemistry Eighth Version by Peter Atkins and Julio De Paula
We’ve got taken the chance to refresh each the content material and presentation of this textual content whereas—as for all its editions—conserving it versatile to make use of, accessible to college students, broad in scope, and authoritative. The majority of textbooks is a perennial concern: we now have sought to tighten the presentation on this version.
Nonetheless, it ought to all the time be borne in thoughts that a lot of the majority arises from the quite a few pedagogical options that we embody (similar to Labored examples and the Information part), not essentially from density of knowledge. Probably the most putting change in presentation is using color.
We’ve got made each effort to make use of color systematically and pedagogically, not gratuitously, seeing as a medium for making the textual content extra engaging however utilizing it to convey ideas and knowledge extra clearly.
The textual content continues to be divided into three elements, however materials has been moved between chapters and the chapters have been reorganized.
We’ve got responded to the shift in emphasis away from classical thermodynamics by combining a number of chapters in Half 1 (Equilibrium), taking into account that a few of the materials will have already got been lined in earlier programs.
We now not make a distinction between ‘ideas’ and ‘equipment’, and in consequence have offered a extra compact presentation of thermodynamics with much less synthetic divisions between the approaches.
Equally, equilibrium electrochemistry now finds a house inside the chapter on chemical equilibrium, the place area has been made by lowering the dialogue of acids and bases.
In Half 2 (Construction) the principal adjustments are inside the chapters, the place we now have sought to deliver into the dialogue modern methods of spectroscopy and approaches to computational chemistry.
In recognition of the most important position that bodily chemistry performs in supplies science, we now have a brief sequence of chapters on supplies, which deal respectively with onerous and smooth matter.
Furthermore, we now have launched ideas of nanoscience all through a lot of Half 2. Half 3 has misplaced its chapter on dynamic electrochemistry, however not the fabric.
We regard this materials as extremely essential in a up to date context, however as a ultimate chapter it hardly ever obtained the eye it deserves.
To make it extra readily accessible inside the context of programs and to acknowledge that the fabric it covers is at dwelling intellectually with different materials within the guide, the outline of electron switch reactions is now part of the sequence on chemical kinetics and the outline of processes at electrodes is now part of the final dialogue of stable surfaces.
We’ve got discarded the Packing containers of earlier editions. They’ve been changed by extra absolutely built-in and intensive Influence sections, which present how bodily chemistry is utilized to biology, supplies, and the atmosphere.
By liberating these matters from their bins, we consider they’re extra doubtless for use and learn; there are end-ofchapter issues on a lot of the materials in these sections.
Within the preface to the seventh version we wrote that there was vigorous dialogue within the bodily chemistry group in regards to the alternative of a ‘quantum first’ or a ‘thermodynamics first’ method. That dialogue continues. In response we now have paid specific consideration to creating the group versatile.
The strategic intention of this revision is to make it doable to work via the textual content in a wide range of orders and on the finish of this Preface we as soon as once more embody two recommended street maps.
The priority expressed within the seventh version in regards to the degree of mathematical means has not evaporated, after all, and we now have developed additional our methods for exhibiting absolutely the centrality of arithmetic to bodily chemistry and to make it accessible.
Thus, we give extra assist with the event of equations, inspire them, justify them, and touch upon the steps. We’ve got saved in thoughts the struggling scholar, and have tried to supply assist at each flip.
We’re, after all, alert to the developments in digital sources and have made a particular effort on this version to encourage using the sources on our Site (at www.whfreeman.com/pchem8) the place you can even entry the eBook.
Specifically, we expect it essential to encourage college students to make use of the Residing graphs and their appreciable extension as Explorations in Physical Chemistry.
To take action, wherever we name out a Residing graph (by an icon hooked up to a graph within the textual content), we embody an Exploration within the determine legend, suggesting the way to discover the implications of adjusting parameters.
General, we now have taken this chance to refresh the textual content completely, to combine purposes, to encourage using digital sources, and to make the textual content much more versatile and updated.
