SRK Equation Vs. Ideal Gas Equation
 
1 Attachment(s)
I need someone who is familiar with the SRK equation to check a number for me. I need to know the pressure at 273K for a gas with these properties: Critical temperature = 425.2K, Critical Pressure = 3797 kPa and the Pitzer acentric factor= 0.1931 and the molar specific volume = 1 m^3/kmol

I'm developing a spreadsheet and graph and I need to make sure it is right. I got about 732.7 kPa which to me doesn't seem quite right. How close or far off should the result be to the ideal gas equation result?

Thanks.

EDIT: I have attached a graph comparing my two values for the gas with the above mentioned characteristics. Does it seem right?
