The following web pages consist of a two frame layout. The left handside frame is the "text" frame which contains references to the illustrations in the right handside "illustration" frame. The back and next arrow keys shown in the navigation bar enable movement through the text. Arrow keys also appear in the "illustration" frame in many instances, but these only control the "illustration" frame's content.

In addition to the next and back buttons, navigation is possible by clicking on the menu bar across the top of the pages. Clicking on an icon once will open a block of relevant links to chose from. Clicking on these links enables navigation through the site. Clicking on the aforementioned icon once more will close the block of links.

Finally I hope that you enjoy viewing these web pages and that it adds to your understanding of the rates of chemical reactions.
