12.18 An insulated tank having a total volume of 0.6m3 is divided into two compartments. Initially one compartment contains 0.4m3 of hydrogen (H2) at 127C,2 bar and the other contains nitrogen (N2) at 27C,4 bar. The gases are allowed to mix until an equilibrium state is attained. Assuming the ideal gas model with constant specific heats, determine a. the final temperature, in C b. the final pressure, in bar. c. the amount of entropy produced, in kJ/K
