14.1 Dynamic Equilibrium, Keq , and the Mass Action Expression
... When making assumptions, if a reaction has a relatively small keq and a relatively large initial reactant concentration, then the concentration change (x) can often be neglected without introducing significant error. This does not mean x = 0, because then this would mean there is no reaction. It mea ...

Ceramics for catalysis
... Once the reactant is bound to the surface, it can readily undergo reactions which take place only with difficulty in the gas or liquid phases. This may result from the close proximity of reactant molecules on the surface and/or the changes in bonding consequent upon chemisorption; both are essential ...
