The apparent yield can sometimes be greater than 100%. In the occurrence of a reverse reaction, some of the anticipated product is likely to react with the reagents to reform the original reactants, resulting in a lower than expected yield.These side reactions subtract from the yield of the main product. These are known as side reactions, and the unintended by-products are called by-products. In many cases, the reactants may take part in other processes.The product of a chemical reaction is rarely found in its pure form, and some may be lost during the purification processes, lowering the yield.The percent yield can be below 100% for a variety of reasons: In other chemical reactions, the actual yield is less than the theoretical yield, resulting in a percent yield below 100%. In these cases, these reactions are called quantitative. The actual yield in many processes is nearly equal to the theoretical yield. The percent yield is calculated with this mathematical formula: The percent yield is the amount of product actually yielded in comparison to the theoretical yield. The theoretical yield of a reaction is the estimated amount of product that will be produced from the use of specific amounts of reactants. Here’s how to calculate percent yield in chemistry in 10 simple steps. Learning how to calculate the percent yield in chemistry is a foundational exercise and has industrial applications. It can also help in troubleshooting reactions that do not produce the desired product. This information can be used to improve the reaction conditions in order to maximize the amount of product that is produced. Percent yield is used to calculate the amount of product that was actually obtained from a reaction. It is defined as the amount of product obtained from a process compared to the theoretical yield. Yield is an important concept in chemistry and chemical engineering. How to Calculate Percent Yield in Chemistry
