The reaction A2 + B2 2AB follows the mechanism: A2 k-1 k1 A + A (fast) A + B2 k2 AB + B (slow) A + B AB (fast) The overall order of the reaction is:
(3) 1.5
Rate is decided by the slow step: r = k2[A][B2]
A is an intermediate; from the fast equilibrium: K = k1k-1 = [A]2[A2]
[A] = K1/2[A2]1/2
r = k2K1/2[A2]1/2[B2]
Overall order = 12 + 1 = 1.5
