The actual yield—the quantity physically obtained from a chemical reaction conducted in a laboratory—is often less than the theoretical yield. [8] The theoretical yield is what would be obtained if all of the limiting reagent reacted to give the product in question. A more accurate yield is measured based on how much product was actually ...
Percentage yield is calculated by dividing the amount of the obtained desired product by the theoretical yield. [6] In a chemical process, the reaction is usually reversible, thus reactants are not completely converted into products; some reactants are also lost by undesired side reaction.
Conversion and its related terms yield and selectivity are important terms in chemical reaction engineering.They are described as ratios of how much of a reactant has reacted (X — conversion, normally between zero and one), how much of a desired product was formed (Y — yield, normally also between zero and one) and how much desired product was formed in ratio to the undesired product(s) (S ...

The theoretical yield strength of a perfect crystal is much higher than the observed stress at the initiation of plastic flow. [18] That experimentally measured yield strength is significantly lower than the expected theoretical value can be explained by the presence of dislocations and defects in the materials.
In reality, the actual yield is not the same as the stoichiometrically-calculated theoretical yield. Percent yield, then, is expressed in the following equation:
Pros and cons of investment-grade bonds vs. high-yield. These two classes of bonds have both differences and similarities. For example, when it comes to income potential, you will earn a smaller ...
Bonds can provide passive income, some of which may be tax-free if you're investing in municipal bonds. The tax-equivalent yield formula can be a useful tool for comparing taxable and tax-free ...
