Because bond formation is exothermic, when two 2as-phase
Chapter 9, Problem 145P(choose chapter or problem)
Because bond formation is exothermic, when two gas-phase atoms come together to form a diatomic molecule it is necessary for a third atom or molecule to absorb the energy that is released. Otherwise the molecule will undergo dissociation. If two atoms of hydrogen combine to form \(\mathrm{H}_{2}(g)\), what would be the increase in velocity of a third hydrogen atom that absorbs the energy released from this process?
