(c)Ammonia gas is diffusing at a constant rate through a layer of stagnant air 1 mm thick. Conditions aresuch  that  the  gascontains  65%  by  volume  of  ammonia  at  one  boundary  of  the  stagnant  layer.  The ammonia  diffusing to  the  other  boundary  is quickly  absorbed  and  the  concentration  is  negligible. The temperature  is  275  K  and  the  pressure  is  atmospheric.  Under  these  conditions the  diffusivity  of ammonia in air is 1.8 x 10-5Estimate the rate of diffusion of ammonia through the layer

Distillation

Distillation is a process/technique to separate more volatile components from less volatile components using the principle of relative volatility. In chemical engineering, distillation is one of the most common and important topics that is involved in almost every industry and process.
