Good afternoon. Is the phase transition from "water1" to "water2" implemented based on the concentration of the substance "water1"?

Program logic :(I assume this)   
#include "udf.h"
if the concentration of "water1" in cell N is <=1, then ....
Define_Source (mass transition)
{
can there be an Arrhenius coefficient here?I do not know how to describe the phase transition rate. 
}
return the concentration in the cell

How to find the zone between "water1" and "gas1" is a solvable task. How to determine the reaction rate is a problem.
