help with #s 5,6,7 step by step I am probably not working these right please help
The Energy of the H-atom's single electron, when bound to the nucleus, is given by the formula E_n = -R/n^2 (Equation 1-4, "Physical Chemistry, A Modern Introduction"). The lowest energy state corresponds to n-1. The electron is unbound when n is infinite. Calculate the energy of the ionizing the H-atom, i.e., the energy to take the system from n=1 to n=infinity. Assume that the Rydberg constant is 13.6 electron volts, and report your answer in electron volts. The energy of translation of a single molecule or atom is given by: E_atom = (p_x^2 + p_y^2 + p_z^2)/2m (Equation 1-31, "Physical Chemistry, A Modern Introduction"). Calculate the speed (in miles/hour) of an atom of Krypton corresponding to an energy of 7kT, where the temperature is 20 degree C and k is Boltzmann's constant. Assume the existence of a system consisting of two energy levels (per molecule). These have energies (level 1) 6kT and (level 2) 21kT (T=300 K). What is the ratio of the population P_2 to the population P_1 for such a system? Calculate the root-mean-square velocities of H_2 ,He, N_2, Cl_2, Ar, and Ne at 20.0 degree C. What is the temperature (in degree C) at which the population of harmonic oscillators in the n=1 state is one quarter of the population of harmonic oscillators in the n=0 state for an oscillator whose vibrational energy is 2.54 x 10^-21 J per molecule. In a system in which there are two energy levels, E_1 and E_2, when the temperature is enormous, i.e., large enough to treat as infinite, calculate the fraction of systems found in the lower (1) level. Assume the existence of a system consisting of two energy levels (per molecule) with energies 3kT and 5kT. The partition function (Q) is then Q = e^-3 + e^-5 Calculate the average energy per molecule. Report your answer as a multiple of kT. (see eqn. 1-28 in the text)
