In$-$Class Example $26$:

Ethane $($at $200$ kPa and $\backslash (50^\{\backslash$circ$\}\backslash$mathrm$\{$C$\}\backslash ))$ and air $($at $300$ kPa and $\backslash (10^\{\backslash$circ$\}\backslash$mathrm$\{$C$\}\backslash ))$ are contained in separate chambers under the conditions shown in the table provided. The two gases are then allowed to mix adiabatically. Find the final temperature and pressure of the final mixture as well as the entropy generated by the mixing. What does the entropy generation indicate?
