i will give UP VOTE! Thank you~

In the gas phase environment, B particles are converted to solid products as follows:

2A (gas) + B (solid) R (gas) + S (solid)

The reaction proceeded according to the shrink core model with reaction control and with a time for complete particle conversion of 1 h. A fluidized bed shall be designed to treat 1 ton/hr solids to 90% conversion using a stoichiometric feed rate of A, fed at CAo. Find the weight of the solids in the reactor if the gases are assumed to be in a mixed stream. Note that the gas in the reactor is not at CAo
