Please work this out for me. I am struggling

Carbon dioxide, CO2, has a critical temperature and pressure of 30.98C and 7.38MPa respectively. It also has an acentric factor of 0.228. a) Use the Peng-Robinson equation of state to plot the pressure for carbon dioxide at 0C as a function of the volume in the range 4105m3mol1 to 0.001m3mol1. (7 marks) b) Use your plot and the Antoine equation presented below to estimate the volume change associated with the phase transformation from a saturated liquid to a saturated yapour. lnPCO2/kPa=15.38T/K2.111956 (8 marks) C) Compare your volume change to a similar value from the literature (make sure to remember to provide a reference for your experimental value).
