 ____________________________________________________ The measured rate law for this reaction is rate = k.         H2(g) + I2(g) → 2 HI(g)         A mechanism for the reaction is:         (1)      I2(g) → 2 I(g)               (2)      H2(g) + 2 I(g) → 2 HI(g)         Which elementary reaction step has the slower rate?
