For NaCl, the ionic radii for Na+ and Cl- ions are 0.102 and 0.181 nm, respectively. If an externally applied electric field produces a 5% expansion of the lattice, compute the dipole moment for each Na+-Cl- pair. Assume that this material is completely unpolarized in the absence of an electric field.
Calculate the theoretical stages needed to separate a 10 mole% ethanol liquid saturated feed into a 80 mole% distillate and a 0.1 mole% bottoms at 1 atmosphere pressure.
