Hint: Use the thermodynamic aG = -5 () = and relation definition of G. (12 p.) 2. Show that the virial equation of state written in the form: pv B(T) C(T) Z = 1 + RT V2 = + Vm m enables predicting critical parameters of a fluid. Calculate the predicted value of a compressibility factor Z PcVmc Zc RTC at critical state: (10 p.) = 3. Prove the following
