Consider two separate containers: container A holds 65.3 g of carbon dioxide gas, container B holds 48.2 g of oxygen gas. The pressure of both gases is 1 bar and the temperature is 298.15 K. Both gases can be treated as ideal gases. Parta) Determine the sum of the entropies of the gases in both separated containers. Part b) Calculate the total entropy of the gas mixture, which is obtained after mixing both gases in one container, while maintaining a constant temperature and pressure. Part c) The gas mixture from part b) is expanded in an isobaric process until its volume has increased by a factor of 2.5. Calculate the entropy of the gas mixture after this process is completed.

Try Again Your answer is wrong. • Second reaction: Your answer for A Sis incorrect. A chemical engineer is studying the two reactions shown in the table below. In each case, he fills a reaction vessel with some mixture of the reactants and products at a constant temperature of 88.0 °C and constant total pressure. Then, he measures the reaction enthalpy AH and reaction entropy AS of the first reaction, and the reaction enthalpy AH and reaction free energy AG of the second reaction. The results of his measurements are shown in the table. Complete the table. That is, calculate AG for the first reaction and AS for the second. (Round your answer to zero decimal places.) Then, decide whether, under the conditions the engineer has set up, the reaction is spontaneous, the reverse reaction is spontaneous, or neither forward nor reverse reaction is spontaneous because the system is at equilibrium. 2Fe₂O3(s) 4Fe(s) + 30₂ (g) ΔΗ = 1648. kJ AS = 4631.
