When two atoms collide some of their kinetic energy may be converted into electronic energy in one or both atoms.

When two atoms collide some of their kinetic energy may be converted into electronic energy in one or both atoms. If the average kinetic (3/2KBT) is about equal to the energy for some allowed electronic transition, an appreciable number of atoms can absorb enough energy an inelastic collision to be raised to an excited electronic stateA) Calculate the average kinetic energy per atom in a gas sample at 298KB)Calculate the energy difference between the n=1 and n=2 levels in hydrogen.C) At what temperature is it possible to excite a hydrogen atom from the n=1 level to the n=2 level by collission
