Suppose there is a total reboiler instead of a partial reboiler. Eqs. (6-10) to (6-12) will be changed and the neat logic of the tridiagonal matrix does not work as well.

Equation (6-10) to (6-12)

a. Derive the mass balance matrix if \(\mathrm{F}_{\mathrm{N}}=0\).

b. Determine how to arrange the calculations to do the mass balances when \(\mathrm{F}_{\mathrm{N}} eq 0, \mathrm{z}_{\mathrm{N}} eq \mathrm{x}_{\mathrm{N}-1}\), and the feed to the total reboiler is a liquid.
