Question

For the reaction, $\mathrm{H}_2(\mathrm{~g})+\mathrm{I}_2(\mathrm{~g}) \rightleftharpoons 2 \mathrm{HI}(\mathrm{~g})$ Attainment of equillibrium is predicted correctly by :

Aicharya · Accepted Answer

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