stoichiometric coefficient

Substrates and products appear in a chemical reaction with specific stoichiometric coefficients.

Key words: buffer capacity, response reaction, heterogeneous system, stoichiometric coefficient.

Any chemical species that is regenerated, such as a catalyst, also has a stoichiometric coefficient of zero.

The stoichiometric coefficients alone are sufficient for the mathematical maximization of a specific objective function.

These coefficients are sometimes called the stoichiometric coefficients.

Here is the stoichiometric coefficient for substance , equal to a, b, p, and q in the typical reaction above.

There are often chemical species present that do not participate in a reaction; their stoichiometric coefficients are therefore zero.

All of the reactions should be divided by the stoichiometric coefficient for the electron to get the corresponding corrected reaction equation.

For elementary (single-step) reactions the order with respect to each reactant is equal to its stoichiometric coefficient.

The stoichiometric coefficient ν represents the degree to which a chemical species participates in a reaction.

This function may be considered as the sum of the reaction rates for deformed input stoichiometric coefficients .

Changes in the stoichiometric coefficients of a balanced cell equation will not change E value because the standard electrode potential is an intensive property.

Elementary (single-step) reactions do have reaction orders equal to the stoichiometric coefficients for each reactant.

Complex (multi-step) reactions may or may not have reaction orders equal to their stoichiometric coefficients.

In reaction mechanisms, stoichiometric coefficients for each step are always integers, since elementary reactions always involve whole molecules.

The stoichiometric coefficient.

The reaction orders (here 1 and 2 respectively) differ from the stoichiometric coefficients (2 and 1).

For elementary reactions or reaction steps, the order and stoichiometric coefficient are both equal to the molecularity or number of molecules participating.

The exponents α, β etc. are explicitly identified for the first time as the stoichiometric coefficients for the reaction.

Let us use the notations , for the input and the output vectors of the stoichiometric coefficients of the rth elementary reaction.

Inserting into the above equation gives a Stoichiometric coefficient () and a differential that denotes the reaction occurring once ().

The exponents x and y are the partial reaction orders and must be determined experimentally; they are often not equal to the stoichiometric coefficients.

When chemical reactions comprise combinations of reactants and products with various isotopic expressions, the stoichiometric coefficients are functions of the isotope substitution number.

The use of k atomic element conservation equations for the mass constraint is straightforward, and replaces the use of the stoichiometric coefficient equations.

Denoting the reactants by A, B ..., each complex species is specified by the stoichiometric coefficients that relate the particular combination of reactants forming them.
