Question

Calculate the total pressure in a mixture of 3.5gr of Dinitrogen , 3gr of dihydrogen and 8gr of dioxygen confined in a vessel of 5dmº at 27°C (R=0.083 bar dm®/k/mole) (Ans:9.3375 bar)​

Answer 1

Answer:

3)A mixture of nitrogen and oxygen (xN2=0.7) behaves as an ideal gas mixture. 50 moles of this mixture at 1 bar and 25 °C are fed into an initially-empty, rigid, diathermal vessel causing the pressure in the vessel to reach 1 bar. Assuming the surroundings are also at 25 °C, calculate the heat transfer needed for the gas mixture in the vessel to be at 25 °C. At this temperature, Cp for nitrogen = 1.040 J/(g K) and Cp for oxygen = 0.918 J/(g K).
