The Demonstration plots the reaction factor for a second-order gas-liquid reaction versus the Hatta number, 
, for various values of the parameters, 
, 
, and 
defined in Details. Two new parameters are introduced and defined by 
and 
; both vary from 
to 
when and vary from 0 to

Details
Consider a second-order reaction between dissolved gaseous species 
and a nonvolatile liquid species 
. The reaction factor for this second-order gas-liquid reaction is given by:
, where 
and 
.
The Hatta number, , is a dimensionless parameter defined as the ratio of the rate of chemical absorption to the rate of physical absorption for species . Here 
(where 
is a stoichiometric coefficient for species ), 
gives ratios of diffusivities and concentrations, and 
and 
are two dimensionless parameters. All parameters are defined in [1].
