Answer to Question #306591 in Chemical Engineering for loli

Question #306591

By what percentage would the rate of absorption be increased or decreased by increasing the total pressure from 100 to 200 KN/m2 in the following cases:

a. The absorption of ammonia from a mixture of ammonia and air containing 10% of ammonia by volume, using pure water as solvent. Assume that all the resistance to mass transfer lies within the gas phase.

b. The same conditions as (a) but the absorbing solution exerts a partial vapour pressure of ammonia of 5 KN/m2. The diffusivity can be assumed to be inversely proportional to the absolute pressure.
