A student is a provided by 500 ml of 600 PPM solution of sucrose.What volume of this solution in millilitres contanis 0.15g of sucrose?

B) Catalyst pellets 5 mm in diameter are to be fluidized with 45000 kg/hr of air at 1 atm and 80 °C in a vertical cylindrical vessel. The density of the catalyst particles is 960 kg/m³, the sphericity is 0.86. If the given quantity of air is just sufficient for fluidize the solids, what is the diameter of the vessel? If air has a viscosity of 0.00002 kg/m. sec and voidage = 0.45.

A gas is stored in a 3-m-outer-diameter spherical container made of 3-cm-thick plastic. Themolar concentration of the gas in the plastic is 0.001 kg/m3 at the inner surface and negligible at theouter surface. The diffusivity of the gas in the plastic is 5 x 10-10 m2/s. The gas is highly toxic so theplastic shell contains a catalyst to degrade the gas into a safe product. The rate of reaction of the drug islimited by the catalyst concentration so it is first order in the gas concentration with rate constant 10-8kg/(m3s).A. Start with a shell balance in spherical coordinates to determine the governing equation. Assume steadystate with zero order reaction.B. Solve the differential equation obtained from the shell balance with appropriate boundary conditions todetermine concentration profile.C. Use the solution for concentration profile to determine rate of diffusion into the air.D. Determine fractional reduction in gas diffusion in air due to incorporation of catalyst in the membrane
