Q27. The gas phase reaction between SiH2 and H20 was studied, and the following mechanism was proposed. M is a buffer gas which takes away energy as heat; you can treat it as a regular reactant. 1) SİH2 + H20 F SİH2-H2O* K 2) SİH2-H2O* + M SİH3OH Assuming that the first step is a pre-equilibrium step and the second step is rate-limiting, derive the rate law for this mechanism.
