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

$1$ point

Styrene is produced from ethylbenzene, as represented by the following equation.

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

Equilibrium Concentrations

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

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

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

If the equilibrium system represented by the equation above was heated, the value of the equilibrium constant would $,i,$ and the concentration of $C_6{H}_{5}C{H}_{2}C{H}_3(g)$ would ii
