" /> stoichiometric number - CISMeF





Preferred Label : stoichiometric number;

Detailed label : stoichiometric number, ν;

IUPAC definition : A chemical reaction of known stoichiometry can be written in general as: \[a{A}\, \,b{B}\, \,...\rightarrow\,...\, y{Y}\, \,z{Z}\] For the reaction products Y and Z the numbers y and z are known as the stoichiometric numbers, ν Y and ν Z, for Y and Z respectively. For the reactants the stoichiometric numbers are the negatives of the numbers appearing in the equation; for example the stoichiometric number ν A for the reactant A is -a. In other words, the stoichiometric numbers are positive for products and negative for reactants.;
