PROVISIONAL LEWIS STRUCTURES T01/S01 For each provisional structure, identify if it is the correct Lewis structure (C) or if it needs to be modified according to procedure MA or MB to obtain the correct Lewis structure. MA. Form multiple bonds to the central atom using lone pair on the terminal atom(s) until the central atom has an octet (or septet). MB. Form multiple bonds to the central atom using lone pair on the terminal atom(s) until the central atom has a formal charge of zero (0) or until two double bonds are formed. A provisional structure has the valence electrons distributed in order as (1) a bond between each pair of atoms, (2) an octet for each ligand (terminal) atom or ligand group (CH3, NH2 or OH) and (3) any remaining electrons on the central atom.

The overall reaction of hydroxide radical with hydrogen gas occurs as follows: OH (g) + H2(g) – H20(g) + H'(g) Part A This reaction plays a significant role in the chemistry of the earth's atmosphere by eventually converting OH to HO, through the subsequent reaction of H with O2. HO2 is involved in the destruction of stratospheric ozone (J. Phys. Chem. A, 2006, 110. 6978). Determine the activation energy for the reaction of OH with H, reaction. O 16.4 kJ mol The rate constants for the reaction of OH with H2 were found to be 1.83x10' L mol s'at 107. °C and 5.68×10° L mol's at 37.
