Question

(3) Mixing of two ideal gases A rigid insulated container contains 12 kg of oxygen at 150 kPa and 280 K separated by a divider from 16 kg of carbon dioxide at 400 kPa and 350 K. The divider is removed and the mixture comes to a uniform state. (a) Find the final temperature and pressure of the mixture. (b) Find the entropy generated during the mixing process in kJ/K.

Step 1

To calculate the number of moles, we can use the ideal gas equation: PV = nRT For oxygen: P = 150 kPa V = unknown (since the volume is not given) n = unknown (number of moles) R = 8.314 J/(mol·K) (universal gas constant) T = 280 K For carbon dioxide: P = 400 Show more…
