WebJan 25, 2016 · For a linear molecule, 1 axis of rotation will have it look exactly the same, so 6-1=5 DoF's. For a bent molecule, a rotation (anything between 0---->360 in each of these cases) about any axis will have it look different. 6-0= 6 DoF's. Multiply that number by 1/2k*T an you have the kinetic energy for the atom (KE). WebJan 15, 2024 · 9.5: Degree of Dissociation. Reactions such as the one in the previous example involve the dissociation of a molecule. Such reactions can be easily described in terms of the fraction of reactant molecules that actually dissociate to achieve equilibrium in a sample. This fraction is called the degree of dissociation.
