Physical Chemistry: Show complete solution.

Two moles of O₂
gas at 1 atm and 10 degrees C are mixed adiabatically with 4 moles of N₂
gas at 1 atm and 80 degrees C to yield a mixture whose pressure is also 1 atm. C_p
of O2 and N2 may be taken as 7 cal/mol-K. What is the entropy change for the process?
