Law of Corresponding state: It states that all the fluids when compared at the same reduced temperature and reduced pressure have approximately the same compressibility factor and all deviate from the ideal gas behaviour to the same extent. Reduced Temperature Tr= (given temperature)/(critical temperature Tc) Reduced pressure Pr= (given pressure)/(critical pressure Pc) So, Carbon dioxide have Tc =304.13 K, Pc = 72.8 atm. Argon has Tc = 150.8 K, Pc = 48.03 atm, Then Argon reduced properties: Tr = 340/150.8 = 2.055 Pr = 32/48.07 = 0.6663. So, Carbon dioxide should have nearly the same reduced properties values to be in the correspondig state. Now, we take this reduced values for carbon dioxide to find the required temperature and pressure. temperature = Tr*Tc = 2.055*304.13 = 624.987 K. Pressure = Pr*Pc = 0.6663*72.8= 48.51 atm.
