Chemical Engineering - Mass Transfer - Discussion

I agree Chemical properties is the correct answer.

Mass transfer is a unit operation, not a unit process so no chemical changes will occur.

Mass transfer is that transfer in which transfer of molecules high concentration to lower concentration with the help of a driving force so that no change in chemical properties Only a change in physical property.

In the presence of a driving force so that no change in chemical properties.

Mass transfer is the net movement of mass from a high concentration gradient to a lower one. So the chemical property doesn't affect the mass transfer operation.

We have to remember that mass transfer is a process of transformation of mass from one phase to another phase. As phase transformation is not a chemical change it depend mainly on physical properties of the two phases.

Because chemical property of fluids is not a role in mass transfer then they not effected.

Good explanation. Thanks all.

Please tell me the explanation.

Consider options: (ASSUMED).

Chemical properties are a good option because consider pure component which is in equilibrium with its vapour in the container. Since all molecules are the same type, why are you considering chemical potential?

Consider the degree of turbulence, if the turbulence is more mass transfer coefficient is very high (penetration theory, surface renewal theory, . ).

Physical properties:for example physical properties like solubility is high we will neglect liquid phase mass transfer coefficient.

Interfacial area: if there is more contact area more availability of collisions and diffusion type mass transfer (penetration theory).

The driving force for the mass transfer is the difference in chemical potential which is a chemical property, so I think it is wrong to say the rate of mass transfer does not necessarily depend on the chemical properties.
