The importance of diffusion in catalyst pellets can often be determined by measuring the effect of pellet size on the observed reaction rate. in this exercise, consider an irreversible first-order reaction occurring in catalyst pellets where the surface concentration of reactant a is cas=0.15 m.
data:
diameter of sphere cm 0.2 0.06 0.02 0.01 0.008 0.006
robs (mol/h/cm3) 0.25 0.8 1.8 2.4 2.5 2.5
a.) calculate internal effectiveness factor for each particle size
b.) identify particles that experience no, negligible, intermediate, or strong diffusion limitation.
c.) estimate the thiele modulus for a catalyst particle of diameter 0.1 cm.

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length of a column of water 1.00 km high for a temperature increase of 1.00ºc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in ×10^{-3} −3 m)
