Using Drago-Wayland Acid/base Parameters-#1
This page provides exercises in using the Drago-Wayland parameters to estimate heats of formation of Lewis acid-base adducts. In order to solve the problems presented, you need a table of the parameters. If you don't have such a table available, ou can click on the "Show Table" button below to display (and print) a table. It's more efficient to use tables generally available in inorganic textbooks. When you press "New Problem", a Lewis Acid/Base reaction will be displayed on the right side of the page. To help you follow the process, the complex is enclosed in brackets with * separating the acid and base. Determine the value of the answer in KJ, paying attention to the sign convention, and submit the answer. The results appear in the table. The pages uses all of the Drago Wayland parameters (Ea,Eb,Ca,Cb,Ra,Tb). You can display the solution by pressing the "Show Answer" button. Pay close attention to the sign of the enthalpy. It is usually negative, but for large values of Ra*Tb it can be positive.
