QUESTION \#2. (a) Derive an expression to predict the flux of naphthalene (C10H1) evaporation that is occurring from the surface of a naphthalene spherical particle having a radius of R. Also, find the equation of required time for the solid naphthalene to disappear. (b) An ammonia (NH1) is diffusing through a thin film of water 4.0mm thick at 278K. The concentration of NH2 at point 1 at one boundary of the film is 2.0 wt %NH3 (density 1=991.7 kg/m3 ), and at the other boundary at point 2 it is 10.0wt%NH3 (density 2=961.7kg/m3 ). The diffusion coefficient of NH3 in water is 1.24109mm2/s. Assuming steady state and water is insoluble in ammonia, calculate the flux of ammonia in kgmol/(5,m2). Comment on your
