mass transfer

In Topic 3.E.2, I presented a model for steady-state reaction and diffusion dz2d2CADABkCA=0 that can be used to model diffusion and the reaction of AC in the orange region illustrated on the right. Solve the equation using the boundary conditions: at z=0,NAZ=NA0, and at z=L,NAZ=0. Here is what I got. CA(z)=kDABNA0[coth(LDABk)cosh(zDABk)sinh(zDABk)]
