Given the $Q-e$ values for styrene $(Q=1\mathrm{.}00,e=-0\mathrm{.}8)$ and $4-$chlorostyrene

$-0\mathrm{.}33$ :

$($a$)$ Calculate the reactivity ratios for styrene and $4-$chlorostyrene.

$($b$)$ Plot the instantaneous copolymer composition as a function of monomer concentration in the

copolymerization mixture.

$($c$)$ Comment on the expected monomer sequence distribution in the resulting copolymer.
