Question:

Gaseous reactant A diffuses through a gas film and reacts on the surface of a solid according to a reversible first-order rate,

-r = k" (CAS- CAe) A

where CA, is the concentration of A in equilibrium with the solid surface. Develop an expression for the rate of reaction of A accounting for both the mass transfer and reaction steps.
