normalized by the volume of each phase), the equations in our papers (2, 3) are mathematically valid.
We agree with the comments of Pankow (1) and regret any confusion that may arise as a result of our definition of Kp (2, 3). Our definition of a dimensionless Kp (i.e., the particle to gas mass ratio) was intended to provide an intuitive representation of the mass distribution between gas and particle phases. Although our definition of Kp is inconsistent with Pankow’s definition (the particle to gas mass ratio,
