order can be established only if one of the two reacting 

 agents is in such great excess that its concentration

remains practically constant despite the reaction. Falk 

 and Winslow (1926) come to the conclusion that the 

 bacterial cells are the agent whose concentration remains 

 constant : 



"If it be assumed that the fundamental reaction of disinfection is 

 unimolecular, we might consider that of the two reacting agents, (1) 

 disinfectant and (2) living cells, one or the other is present in excess 

 and that its concentration is not changing significantly during the
