In the previous two chapters, we have been zooming into mass transfers across an interface and the partition coefficient. In this chapter, we will further combine these topics and dive deeper into the world of mass transfers.

In the past, we have studied heat transport more elaborately than mass transfer. Now, we are going to use the same skill set as used for heat transfer and apply it for mass transfer. You will notice that there are many similarities in the overall transfer coefficient, and you will see that penetration theory is also applicable in mass transfer situations.
