hght transmlsslon method of measunng mterfacmJ areas m agttated vessels 1s compared wcth the chemical method The chenucal method 1s seen to yield consistently higher values of mterfacml areas A poss&le explanabon for t.hu Lscrepaocy, based on large mass transfer coefficsents m the lmpelkr regon, IS advanced A consequence of these large mass transfer coefficients 1s that the reaction IS not sufticlentiy enhanced near the unpeiler reson THIS then uaphcs that the rate IS not independent of hydrodynamics m the unpeller reson tNlTtOlKICllON
