How much product can one obtain from a reaction?
This question is at the heart of what most chemists do. Much of organic chemistry is an attempt to improve reaction yields. Reactions will often have such poor yields that a particular multi-step synthesis is not worth conducting until certain steps can be improved. In general, the study of thermaodynamics is concerned the spontaneity of chemical reactions and the extent of reaction. In this Chapter we begin the process of answering the question by studying reaction stoichiometry to determine which reagent is limting and which reagent is presentin excess. In some instances the reactatns are present in precisely the required stoichiometry ratios. Then there is no limiting reagent. A systematic approach will make the reasoning accessible to you.
Concentration conversions
We will obtain a deeper understanding of the various units of concerntration by learning how to convert from one to the other. The approach taken is to systematically work through the various combinations. By studying these various systematic conversions these problems become relatively easy.
