Question

Write the correct form of the convection-diffusion equation (BSL 18.0-1) for the following situations:

a. Species “A” diffuses to a catalytic wall where it is instantly converted to pure “B”.

b. Volatile liquid “A” evaporates into a vapture that is initially pure “B”. Note that this is a transient phenomenon

c. Solute species “B” leaches out of a porous plastic slab immersed in liquid.

Clearly state the reasons for the simplifications you made (or didn’t make).
