Reaction Factor for Second-Order Gas-Liquid Reactions
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 .
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 .
