Bond energy has been defined in the text as the amount of energy required to break a chemical bond, so we have come to think of the addition of energy as breaking bonds. However, in some cases the addition of energy can cause the formation of bonds. For example, in a sample of helium gas subjected to a high-energy source, some He2 molecules exist momentarily and then dissociate. Use MO theory (and diagrams) to explain why He2 molecules can come to exist and why they dissociate.
Answer to relevant Questionsa. A flask containing gaseous N2 is irradiated with 25-nm light. Using the following information, indicate what species can form in this flask during irradiation. N2(g) → 2N(g) ΔH = 941 kJ/ mol N2(g) → N2+(g) + e- ΔH = ...Use the MO model to explain the bonding in BeH2. When constructing the MO energy-level diagram, assume that the Be 1s electrons are not involved in bond formation. For the following reaction profiles, indicate The positions of reactants and products. The activation energy. ΔE for the reaction. The second reaction profile is representative of a reaction that occurs by a two-step ...One of the concerns about the use of Freons is that they will migrate to the upper atmosphere, where chlorine atoms can be generated by the reaction Chlorine atoms can also act as a catalyst for the destruction of ozone. ...Sulfuryl chloride (SO2Cl2) decomposes to sulfur dioxide (SO2) and chlorine (Cl2) by reaction in the gas phase. The following data were obtained when a sample containing 5.00 × 10-2 mole of sulfuryl chloride was heated to ...
