Assume that the molecules of the nitrogen gas interact through the potential of the previous problem. Making use of the experimental data given below, determine the ``best'' empirical values for the parameters r0, r1 and u0/k:
T (in K)a2λ3 (in K per atm)100−1.80200−4.26×10−1300−5.49×10−2400+1.12×10−1500+2.05×10−1
