$($a$)$ Plot the effectiveness factor for spherical catalyst$-$particle geometry in the case of

first$-$order reactions, using the expression $($Case $2)$ given in Table $5\mathrm{.}1.$ Use values of

$in[0\mathrm{.}1,10]$ and $Bi=0\mathrm{.}1,2,$ and $10.$

$($b$)$ Comment on the behavior of $$ in the limits of small and large $$ values.
