(one-step reaction)\ Mechanism B\ (1)

,I_(2)(g)_(k_(-1))^(k_(1))2I(g)

\ (fast, equilibrium)\ (2)

,H_(2)(g)+2I(g)->k_(2)2HI(g)

\ (slow)\ Mechanism C\ (1)

,I_(2)(g)_(k)^(k_(1))2I(g)

\ (fast, equilibrium)

The reaction described by H2(g)+I2(g)2HI(g) has an experimentally determined rate law of rate=k[H2][I2] Some proposed mechanisms for this reaction are: Mechanism A (1) H2(g)+I2(g)k12HI(g) (one-step reaction) Mechanism B (1) I2(g)k1k12I(g) (fast, equilibrium) (2) H2(g)+2I(g)k22HI(g) (slow) Mechanism C (1) I2(g)k12I(g) (fast, equilibrium)
