Even when a mechanism is consistent with the rate law,later work may show it to be incorrect. For example, the reaction between hydrogen and iodine has this rate law: rate k[H₂][I₂].The long-accepted mechanism had a single bimolecular step; thatis, the overall reaction was thought to be elementary:H₂(g)+I₂(g) →2HI(g)In the 1960s, however, spectroscopic evidence showed the pres-ence of free I atoms during the reaction. Kineticists have since proposed a three-step mechanism:(1) I₂(g) ⇌2I(g)[fast] (2) H₂(g)+ I(g) ⇌ H₂I(g)[fast](3)H₂I(g )+I(g ) ⇌ 2HI(g ) [slow] Show that this mechanism is consistent with the rate law
