2PRACTICE PROBLEM
The contact process, a method for manufacturing sulfuric acid, has the following mechanism:
2 SO2(g) + O2(g) ⇌ 2 SO3(g) Faster, reversible
SO3(g) + H2SO4(l) → H2S2O7(l) Slow, rate-determining
H2S2O7(l) + H2O(l) → 2H2SO4(l)
The overall reaction for the process has the following experimental rate law: Rate = k[SO2]2[O2].
Is the mechanism given above consistent with the experimental rate law?
