$-\frac{\mathrm{d}\left[{\mathrm{H}}_2\right]}{\mathrm{dt}}=-\frac{\mathrm{d}\left[{\mathrm{I}}_2\right]}{\mathrm{dt}}=-\frac{\mathrm{d}[\mathrm{HI}]}{\mathrm{dt}}$

$\frac{\mathrm{d}\left[{\mathrm{H}}_2\right]}{\mathrm{dt}}=\frac{\mathrm{d}\left[{\mathrm{I}}_2\right]}{\mathrm{dt}}=\frac{1}{2}\frac{1\mathrm{d}[\mathrm{Hl}]}{\mathrm{dt}}$

$\frac{1}{2}\frac{\mathrm{d}\left[{\mathrm{H}}_2\right]}{\mathrm{dt}}=\frac{1}{2}\frac{\mathrm{d}\left[{\mathrm{I}}_2\right]}{\mathrm{dt}}=-\frac{\mathrm{d}[\mathrm{HI}]}{\mathrm{dt}}$

$-2\frac{\mathrm{d}\left[{\mathrm{H}}_2\right]}{\mathrm{dt}}=-2\frac{\mathrm{d}\left[{\mathrm{I}}_2\right]}{\mathrm{dt}}=\frac{\mathrm{d}[\mathrm{HI}]}{\mathrm{dt}}$
