One mole of N2 at 293.65Kand 6.00bar undergoes a transformation to the state described by418.15K abd 2.75bar. Caculate ? S if
Cp,m / Jmol^-1*K^-1 =30.81 - 11.87x10^-3(T/K) + 2.3968 x 10^-5 (T/K)^2     
                                    -1.0176 x 10^-8 (T/K)^3

      Change in entropy is given by
           ? S = S(Tf) -S(Ti)
                 = ?tfti (Cp/T)dT
      Just integrate the given expression with the limits toget the answer.
      Hope this helps!
