A rigid vessel is divided into two parts by a partition. The vessel contains 2 mol of chlorine at 100C and 15 bar on one side and 3 moles of helium at 150C and 10 bar on the other side. The partition is removed and the gases are mixed adiabatically and completely. Assume chlorine is an ideal gas with Cv=7/2R and helium to be an ideal gas with Cv=5/2R. What is the total volume of the vessel in cubic meters (use three decimal places)? What is the final temperature in Kelvin when the partition is removed (use three decimal places) What is the final pressure after the partition is removed in bar (ie 10.25 bar). What is the change in entropy strictly due to mixing (ie not due to changes in T and P)? What is the total change in entropy including changes in T and P?

Do not copy answers from other websites they all are wrong

use Cp while calculating the final temp do not give me the handwritten solution, give me a typed solution
