Question 9 A rigid vessel initially contained carbon dioxide (CO2) gas

Question 9 A rigid vessel initially contained carbon dioxide (CO2) gas at 32C and pressure P. Ethylene (C2H4) gas is pumped into the tank until a mixture of 20 mol %CO2 and 80mol%C2H4 is produced within the tank at 43C and 110 bars. Calculate: i) The volume of the tank using the Kay's rule [8 marks] ii) The value of initial pressure P of CO2 [5 marks] [Data: Critical values:- Tcc(CO2)=304.25K;Tc(C2H4)=282.4K;Pc(CO2)=7.38MPa;Pc (C2H4)=5.04MPa;]
