Monophasic Unidirectional Reactions

It should be emphasized that in the case that A is in deficiency over other reactants, B etc., then k, relating to loss of A, is a pseudo rate constant and the effect of the other reactants on the rate must still be assessed separately (Sec. 1.4.4). 

We shall first consider some straightforward kinetics, in which the loss of A, in the treatment referred to above, is monophasic and the reaction is unidirectional, that is, it leads to 95% loss of A.
