What is the internal energy of an ensemble of 1 mole of particles having two non-degenerate electronic energy levels separated by 1000cm^-1 at 1310K? Only consider the contribution coming from the electronic particion function. Hint: U =- (d lnQ/d beta)‚ ; Q = q^N/ (N!) , where N is the total number of particles.
