Solve Problem $3\mathrm{.}7,$ which is the effectiveness factor for a first order

reaction in a spherical pellet. Generate a plot that is analogous to

Figure $3\mathrm{.}6\mathrm{.}1-1$ of the dimensionless concentration profiles in the pellet

using Thiele moduli of $0\mathrm{.}5,1,2,5,10$ and $20.$ Do the same for Figure

$3\mathrm{.}6\mathrm{.}1-2$ using the expressions of the effectiveness factor for a $1-$D slab

catalyst, an infinite cylinder, and a sphere.
