An 8-molar hydrochloric acid solution [SG = 1:12, C_p = 2:76 J/(g °C)] is produced by absorbing hydrogen chloride [HCl(g)] in water. Liquid water enters the absorber at 25°C and gaseous HCl is fed at 20°C and 790 torr absolute. Essentially all of the HCl fed to the column is absorbed. Take one liter of product solution as a basis of calculation.

(a) Estimate the volume (liters) of HCl that must be fed to the absorber.

(b) Estimate the heat (kJ) that must be transferred from the absorber if the product solution is to emerge at 40°C.

(c) Estimate the final solution temperature if the absorber operates adiabatically.

(d) Briefly describe how you might have used this experimental system with the absorption column heavily insulated to estimate
