2. Estimate the pressure of five moles of nitrogen gas at 152.6C in a four-litre container using the virial equation of state truncated at the second coefficient, which is Z=1+B(T)RTP where B(T)=(B0+B1)RTc/PcB0=0.0830.422/Tr1.6B1=0.1390.172/Tr4.2 Subject to Tr>0.686+0.439Pr Comment on the validity of the estimated pressure. Data: critical temperature of nitrogen; Tc=126.2K; critical pressure of nitrogen, Pc= 3.394 MPa; acentric factor of nitrogen, =0.04
