If $k$ is the mass transfer coefficient and $D_{v}$ is the molecular diffusivity, which one of the following statements is NOT CORRECT with respect to mass transfer theories?
- For Film theory, $k \propto D_{v}$
- For Penetration theory, $k \propto D_{v}^{1 / 3}$
- For Surface Renewal theory, $k \propto D_{v}^{1 / 2}$
- For Boundary Layer theory, $k \propto D_{v}^{2 / 3}$
