The rate determining step would be the slow step. Thus, Step 2 which is bimolecular is the rate determining step. I believe the correct answer from the choices listed above is option C. The reasonable conclusion would be that it <span> is second order overall because step 2 is bimolecular. Hope this answers the question.</span>
Lithium is in the first column of the periodic table and thus can only form one bond with another atom (its ion is Li+)
Oxygen can form two bonds (as in the dioxygen O2).
Hence if you conbine Li and O it has to be Li2O.
I am sure it's the first one.
