3.18 Ten moles of H₂ and two moles of D₂ are mixed at 25 °Cand 1 bar. What is the value of AS°? Assume ideal gases.7. Problem 3.18 Modify the problem so that 2 moles of O₂ and 8 moles of N₂ are mixed. Otherdetails remain the same. Before you start, predict the sign of AmixS. For this problem, use thethermodynamic approach (eqn 3.43)−n₁ R ln y₁ − n₂R ln y₂Amix S=4x = -8.314 (2₁151 +86181)=41.603 5/1Гли8. Calculate AmixS again, for the mixing process described in problem 7. This time, use themolecular interpretation of the entropy (eqn 3.46). You can imagine two vessels connectedtogether with a valve. Initially, oxygen is on one side and nitrogen is on the other, both at 1 bar.Now open the valve and allow mixing; the pressure will still be 1 bar. Calculate AS for theoxygen, as its molecules now explore a volume that is 5 times larger. Calculate AS for thenitrogen, as its molecules now explore a volume that is 1.25 times larger. Add these two ASvalues together to get the total entropy change, which is AmixS. You should get the same answeras in problem 7.

The objective of the question is to calculate-The value of the standard entropy change.The value of…
