A general formalism for defining and identifying limiting reagent in closed systems is proposed and it is correlated to usual definitions and identification methods. An alternative definition of limiting reagent is proposed, based on real situations after the reaction is complete. Useful equations relating the limiting reagent to products and excess reagents (if the limiting reagent is completely consumed or not) and to reaction yields are given and briefly applied.

[18]  The term “stoichiometric amount of substance” has been used before: see [19], for instance. It is the amount of substance added or subtracted from the system according to this definition. However, I believe the term have a proper use as I propose here, using “stoichiometric amount of substance” to designate the amount of substance “normalized” by its stoichiometric coefficient.

[22]  Reaction extent at time t is defined as and it is always positive, since for reagents and , and for products and . It is frequently used in “equilibrium tables” in the form of (without “t”, mostly), if V is volume. For an advisable reading about its importance and scope, consult [23].

[26]  Here it is assumed the stoichiometric coefficients do not change through the reaction, or that the reaction has a time-independent stoichiometry. For a brief comment on this matter, consult [27].

[28]  The symbol “” stands for “conditional” or “implication” arrow, and means “if… then …”. Given two propositions p and q, means “if p, then q”.
[29]  The symbol “” stands for “biconditional” or “equivalence” arrow. The expression “” means “p if and only if q”, that is to say the following implications hold: and .
[30]  Notice that eqs 32 and 33 have the following notation according to “stoichiometric amount of substance” definition: (eq 32) and (eq 33).
