15. (a) (i) Consider a system of weakly interacting particles in equilibrium at temperature T. Carefully discuss the circumstances under which it is valid to assume that the number of particles occupying a state of energy e is directly proportional to exp(-€ /KT). [4] (ii) For an ideal gas, explain why the number of particles travelling with speed between v and v+dy is directly proportional to vexp(-mv² /2kT)dy where mis the particle mass. [4]
