Cooling a Gas Mixture. It is required to cool a gas mixture composed of 75 mol % N₂, 15 mol% CO₂ and 10 mol % O₂ from 800 °C to 350 °C. Determine the cooling duty of the heat exchanger in J/mol if the heat capacity expressions are in the form CP (J/mol.K) = a + bT +cT² + dT³ where the coefficients a, b, c, and d are given by b x 10² - 0.1570 1.5192 5.9768 Species N₂ 0₂ CO₂ a 28.882 25.460 21.489 T[=] K CX 105 0.8075 - 0.7150 - 3.4987 d x 105 - 2.8706 1.3108 7.4643
