The Limiting Reagent and the Extent of Reaction Concepts. (For example, in the reaction 2 H 2 O 2 2 H 2 O, A is H 2, a is 2, B is O 2, b is 1, C is H 2 O, c is 2, and there is no D. ) Furthermore, let's imagine that we start the reaction with only arbitrary initial amounts of reactants A and B and no products.Sep 10, 2012 Professor Morrison shows how extent of reaction xi may be used to keep track of mass balances in reactive systems.

Equilibrium: The Extent of Reactions. Chemical equilibrium studies the extent of reactions and the ways it can be altered Kinetics and equilibrium are two different aspects of chemical reactions (fast reactions may proceed to a great, lesser or a limited extent; same is true for slow reactions) 16. 1 The Dynamic Nature of the Equilibrium State.
Chemists define the extent of reaction as: nAfnAi vA where nAf is the moles of A once the reaction reaches equilibrium, nAi is the moles of A before the reaction began, and vA is stoichiometric coefficient of A for this reaction. The numerator makes physical sense, Extent of Reaction. where A is any chemical species involved in the reaction, its stoichiometric coefficient, and and the moles of species A at the beginning of the reaction and when the extent of reaction is reached, respectively. The sign of in eq 1 is positive for the products and negative for the reactants,extent of reaction example Extent of Reaction. The extent of reaction approach to solving multiple reaction systems is a general formulation that works for many reaction systems. It can be used whenever you know: the complete composition of either the inlet or the exit stream from a reactor,
