A distillation column with \(8.01 \mathrm{~m}\) of packing operating at total reflux separates methanol from ethanol at \(101.3 \mathrm{kPa}\). Average relative volatility is 1.69 . Methanol mole fractions are \(\mathrm{y}_{\text {out }}=0.982\) and \(\mathrm{y}_{\text {in }}=\) 0.016 .

a. Determine the average \(\mathrm{H}_{\mathrm{OG}}\) using Eq. (16-113) (in Problem 16.C3).

Equation (16-113)

b. Check your results for part a using Eq. (16-23) with values of \(y-y *\) determined from Eq. (2-7b) using \(\mathrm{y}=\mathrm{x}\) for total reflux.

Equation 16-23

Eq.(2-7b)
