Step-by-step solution

H2( g)+\mathrm{H}_2(\mathrm{~g})+\mathrm{I}2( g)⇌2HI( g)_2(\mathrm{~g}) \rightleftharpoons 2 \mathrm{HI}(\mathrm{~g}) Concentrations of H2( g)\mathrm{H}_2(\mathrm{~g}) and I2( g)\mathrm{I}_2(\mathrm{~g}) decrease with time while concentration of HI(g)\mathrm{HI}(\mathrm{g}) increases with time. At equilibrium H2( g),\mathrm{H}_2(\mathrm{~g}),\mathrm{I}2( g)_2(\mathrm{~g}) and HI(g)\mathrm{HI}(\mathrm{g}) attain constant values. Correct plot of molar concentration with time is
