Consider the following reaction,
\[
\mathrm{H}_{2}(\mathrm{~g})+\mathrm{X}_{2}(\mathrm{~g}) \longrightarrow 2 \mathrm{H} X(\mathrm{~g})
\]
where, \( X=\mathrm{F}, \mathrm{Cl}, \mathrm{Br} \) and \( \mathrm{I} \).
The order of reactivity of \( X_{2} \) towards hydrogen is
(a) \( \mathrm{F}_{2}\mathrm{Cl}_{2}\mathrm{Br}_{2}\mathrm{I}_{2} \)
(b) \( \mathrm{Cl}_{2}\mathrm{Br}_{2}\mathrm{F}_{2}\mathrm{I}_{2} \)
(c) \( \mathrm{I}_{2}\mathrm{Br}_{2}\mathrm{Cl}_{2}\mathrm{F}_{2} \)
(d) \( \mathrm{I}_{2}\mathrm{Cl}_{2}\mathrm{F}_{2}\mathrm{Br}_{2} \)
