Error in neglecting the convection term in evaporation (a) Rework the problem in the text in S18.2

Question:

Error in neglecting the convection term in evaporation

(a) Rework the problem in the text in S18.2 by neglecting the term x_A (N_A + N_B) in Eq. 18.0-1. Show that this leads to this is a useful approximation if A is present only in very low concentrations.

(b) Obtain the result in (a) from Eq. 18.2-14 by making the appropriate approximation.
