A paper by Ruckenstein and Tsai (1981)* shows that an "optimum pore size" can exist for catalytic reactions of large solute molecules in solvent-filled pores. Obtain the paper from your library and read it carefully. Then derive the analytical equation for the optimum pore size (λopt in the paper) using the expression for De given by equation (11) of the paper. Finally, attempt to verify by calculation λcpt = 0.18, as claimed by the authors in equation (15) of the paper.
The catalyst is in the form of 1/16th inch (1.588 mm) beads with average bulk density of 700 kg/m3 . Design, size, and cost a reactor for making 200,000 metric tons per year of cyclohexane using this process.
Into a barrel containing 33.2 bbl (US) of water containing 0.0012 mol/L of a blue dye you pour V2 yd3 of water containing 8.91 M of the dye. The final concentration of the dye in the barrel is 7.91 mol/m3 after it's well-mixed. What is V2 is yd^3?
with an atomic weight of 51.9405 amu, 9.50% of 53Cr, with an atomic weight of 52.9407 amu, and 2.37% of 54Cr, with an atomic weight of 53.9389 amu. On the basis of these data, confirm that the average atomic weight of Cr is 51.9963 amu.
