Which rate law fits with this mechanism? 2NO --> N2O2 fast step 1 N2O2 + H2 --> N2O + H2O slow step 2 N2O + H2 --> N2 + H2O fast step 3 Question 9 options: rate = k [NO] [N2O2] [H2] rate = k [NO] rate = k [NO]2 [N2O2] [H2] rate = k [NO] [H2] rate = k [NO]2 rate = k [N2O2] [H2] rate = k [NO]2 [H2] [N2O2] rate = k [NO]2 [H2]
propan-1-ol → propene + water C₃H₈O (l) → C3H6 (g) + H2O (l) is considered an Elimination E2 reaction. An E2 Elimination is apparently where an external base is added, so the rate law should be rate = k[C₃H₈O][Base] however the rate law I have is only = k[C₃H₈O]. However, in this reaction, it seems no bases are involved because the catalyst being used is sulfuric acid, which is definitely not a base. Can someone help me with what I am missing here? What factors affect the rate of E2 elimination? Some say that one factor is a strong attacking base -- which I do not think I have. Please help!! I am so very lost
