S₂0² + SO² + 2 OH3 SO² + H₂O.
The following mechanism has been proposed:
i
S₂0² +SO₁²-k₁S₂0₁²+ So₂²-
S₂0₂² + H₂O -- 2 SO² + 2 H+
H+ + OH -k→ H₂O (fast equilibrium to be discussed)
iii
Steady-state approximation follows these steps:
What is or are the intermediates I?
Use which step to give the rate law that may involve [1]?
Express the rates of producing and consuming intermediate(s)
Express [1] of intermediate(s) in terms of [Reactants]
Derive the rate law in terms of [Reactants]
Discuss value and units of the rate constant?
