Repeat the numerical integration in Example 15-5, except use the quadrature formula, Eq. $(9-12)$

Example 5-5

A steady-state system of ethanol and water has equimolar counterdiffusion across a

Equation (9-12)

liquid film of thickness 1.2 10-5m. At z = 0, the ethanol

A steady-state system of ethanol and water has equimolar counterdiffusion across a liquid film of thickness 1.2 10-5m. At z = 0, the ethanol mole fraction is 0.010, and at z = L, the ethanol mole fraction is 0.300. Operation is at 40C. Find the flux of ethanol.
