Q#1 GATE CH 2016 NAT +2 marks -0 marks

A gas obeying the Clausius equation of state is isothermally compressed from 5 MPa to 15 MPa in a closed system at 400 K. The Clausius equation of state is P =  where P is the pressure, T is the temperature, v is the molar volume and R is the universal gas constant. The parameter b in the above equation varies with temperature as b (T) = b0  + b1 T with b0 = 4 x 10-5 m3 mol-1 and b1 =1.35 x10-7 m3 mol-1 K-1. The effect of pressure on the molar enthalpy (h) at a constant temperature is given by .Let hi and hf denote the initial and final molar enthalpies, respectively. The change in the molar enthalpy hf – hi (in J mol‒1, rounded off to the first decimal place) for this process is _______
