Answer to Question #299364 in Chemical Engineering for SAVARA RAVITEJA

Question

Ammonia is being absorbed from air-ammonia mixture by

sulphuric acid solution. The concentration of ammonia 2.5 cm from the acid

surface is 40% by volume and concentration at the acid surface is zero. The

total pressure of the system is 400 mm Hg and the temperature is 288 K. The

value of diffusivity is 1.73 X 10-5 m2

/s at 293 K and 1 atm. Calculate the

following:

(i) Rate of absorption of ammonia across 0.045 m2

of acid surface.

(ii) Concentration of ammonia 1.25 cm from the acid surface
