Question

Alcohol vapour is diffusing through a layer of water vapour and 1 atm pressure. The molal concentration of alcohol on the two sides of the gas film ( water vapour) 0.3 mm thick are 30% and 10% respectively. Assuming the diffusivity of alcohol-water vapour to be U poder equimolar counter diffusion at 35 °c 0.18 cm2/s. X0107% COXn Calculate the rate of diffusion of water vapour in kg/hr through an area of 100 cm2 ​

Answer 1

Answer:

Alcohol vapour is diffusing through a layer of water vapour under equimolar counter diffusion at 35°C and 1 atm. pressure. The molal concentration of. alcohol on the two sides of the gas film (water vapour) 0.3 mm thick are 80%
