Question
The first-order, irreversible reaction (AB) takes place in a 0.3 cm radim penal
catalyst pellet at 7-450 K. At 0.7 atm partial pressure of A, the p
rate is -2.5x 10 mol (gs). Determine the production rate at the
0.15 cm radius spherical pellet. The pellet density is -0.85
diffusivity of A in the pellet is D-0.007 cm
Hint:
The first-order, irreversible reaction (A > B) takes place in a 0.3 cm radius spherical catalyst pellet at T-450
K. At 0.7 atm partial pressure of A, the pellet's production rate is -2.5 x 105 mol/(g s). Determine the
production raté at the same temperature in a 0.15 cm radius spherical pellet. The pellet density is p.- 0.85
g/em'. The effective diffusivity of A in the pellet is Da 0.007 cm'/s
