The interaction of the venom and the antivenom with the receptor sites can be modeled as a reaction engineering catalysis problem. Examples of the reactions are given below. Note that the adsorption of venom on the receptor site is irreversible while the adsorption of antivenom on the receptor site is reversible.

Description	Mechanism	Rate Law
Adsorption of venom onto the receptor site		Rate constant = kv
Adsorption of antivenom onto the receptor site		Forward rate constant = ka Backward rate constant = kia
Reaction of venom with antivenom on the site		Rate constant = ksa
Reaction of antivenom with venom on the site		Rate constant = ksv
Reaction of antivenom and venom in the blood		Rate constant = kp
Removal of antivenom from the system		Rate constant = koa
Removal of venom from the system		Rate constant = kov
Removal of neutralized venom/antivenom product from the system		Rate constant = kop

V = venom
A = antivenom
S = unoccupied receptor site
VS = site occupied by venom
AS = site occupied by antivenom
AV = neutralized product from venom/antivenom reaction
