Chemistry - Chemical Equilibrium Question with Solution | TestHub

In a$\mathrm{10 }\mathrm{}\mathrm{l}\mathrm{i}\mathrm{t}\mathrm{r}\mathrm{e}$box$\mathrm{2.5 }\mathrm{}\mathrm{m}\mathrm{o}\mathrm{l}\mathrm{e}$hydroiodic acid is taken. After equilibrium$2\mathrm{H}\mathrm{I}\rightleftharpoons {\mathrm{H}}_2+{\mathrm{I}}_2$the concentration of$\mathrm{H}\mathrm{I}$is found to be$0.1\text{mol}{\text{L}}^{-1}$. The concentration of$\left[{\mathrm{H}}_2\right]$at equilibrium in mol${\mathrm{L}}^{-1}$, is
