The autocatalytic reaction a + b rightarrow 2b is carried out isothermally in a moving bed reactor. the reaction is elementary, follows separable catalyst decay kinetics, and the decay law is zero order but first-order in concentration of b. write the differential equations and all supporting equations that you would need to solve in polymath including initial and final conditions. additional information: c_a0 = 0.1 mol/dm^3 c_b0 = 0.01 mol/dm^3 k = 350 dm^6/mol middot kg cat middot min k_d = 6.0 dm^3/min middot mol u_s = 8 kg/min f_a0 = 20 mol/min w = 24 kg

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.

i think its 100

i hope this !
