Q1: 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. By what percentage would the rate of absorption be increased or decreased by increasing the total pressure from 100 to 200 kN/m². The diffusivity can be assumed to be inversely proportional to the absolute pressure.
