(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
