Polystyrene, a plastic used for insulation, is manufactured from styrene.

$1$ point Styrene is produced from ethylbenzene, as represented by the equation below. The value of the equilibrium constant, $Kc,$ for the system at equilibrium represented by the equation above is

$C_6{H}_{5}C{H}_{2}C{H}_3(g)+$ energy $C_6{H}_{5}CHC{H}_2(g)+H_2(g)$

Equilibrium Concentrations

$[C_6{H}_{5}C{H}_{2}C{H}_3((g))]=0\mathrm{.}330mo\frac{l}{L}$

$[C_6{H}_{5}CHC{H}_2((g))]=0\mathrm{.}540mo\frac{l}{L}$

$[H_2((g))]=1\mathrm{.}20mo\frac{l}{L}$
