Explain how to determine the proportionality constant, k, for a sample of gas

The wavefunction Atomic wavefunctions are usually expressed in spherical polar coordinates – give value of ψ at any point in space specified by r, θ and φ Can write ψ(r,θ,φ)=R(r)Y(θ,φ) – R(r) is radial part of wavefunction – Y(θ,φ) is angular part of wavefunction Quantum numbers Each of the solutions to the Shrödinger equation is labeled by a set of quantum numbers n, l and m l – n - principle quantum number, l - angular momentum quantum number, m - magnetic l quantum number For the hydrogen atom– n determines the energy and size of the orbital » can be any integer – l determines the shape of the orbital » any integer between (n-1) and 0 – m letermines the orientation of the orbital
