Webthe Hatta number. The physical significance of the Hatta number can be gauged by expressing it as a rate of two terms constants reaction time diffusion time t t k D Ha R A … WebThe Hatta number (Ha) was developed by Shirôji Hatta, who taught at Tohoku University. It is a dimensionless parameter that compares the rate of reaction in a liquid film to the rate of diffusion through the film. For a second order reaction (rA = k2CBCA), the maximum rate of reaction assumes that the liquid film is saturated with gas at the interfacial concentration …
