The three properties are found to be: The property holds. In this reaction, 90% of substance A is converted (consumed), but only 80% of the 90% is converted to the desired substance B and 20% to undesired by-products C. So, conversion of A is 90%, selectivity for B 80% and yield of substance B 72%. See more 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 … See more Yield in general refers to the amount of a specific product (p in 1..m) formed per mole of reactant consumed (Definition 1 ). However, it is also defined as the amount of product produced … See more For batch and continuous reactors (semi-batch needs to be checked more carefully) and the definitions marked as the ones generally found in the literature, the three concepts can be combined: $${\displaystyle Y_{p}=X_{i}\cdot S_{p}}$$ For a process with … See more The following assumptions are made: • The following chemical reaction takes place: where See more Conversion can be separated into instantaneous conversion and overall conversion. For continuous processes the two are the same, for batch and semi-batch there are … See more Instantaneous selectivity is the production rate of one component per production rate of another component. For overall selectivity the same problem of the conflicting definitions exists. Generally, it is defined as the number of moles of desired product per … See more • Werner Kullbach: Mengenberechnungen in der Chemie.
