The solution of simple kinetic equations is analyzed without referencing any topic from differential equations or integral calculus. Guided by the physical meaning of the rate equation, a systematic procedure is used to generate an approximate soluti

Learning how to estimate thermodynamic quantities and how to use estimates extends the usefulness of thermodynamic analyses of chemical reactions. Estimating helps chemists understand why chemical reactions occur and why the outcomes change with temp

Some solutes can exist in aqueous solution in more than one form. Nicotine is an example of such a solute, as are amino acids and other substances that can exist in more than one state of ionization in water. This paper shows how to express the fract

Rising temperature is generally said to reduce the solubility of gases in liquids, yet the facts disagree with any such generalization.
