For binary distillation with \(\mathrm{CMO}, \mathrm{v}_{\text {ref,mol }}=0\). If \(\mathrm{CMO}\) is valid, show that \(\mathrm{v}_{\text {ref,mass }} eq 0\) if \(\mathrm{MW}_{\mathrm{A}} eq \mathrm{MWB}_{\mathrm{A}}\), and calculate the functional form for \(\mathrm{v}_{\text {reff,mass }}\) that will make convection zero in this reference frame. Do this for diffusion in the vapor assuming an ideal gas.
