Describe the evolution of phases and phase compositions as the temperature is gradually increased to 80C. 12.13. Consider an ethanol(1)/ethyl acetate(2) mixture with x1 = 0.20, initially at 80C and 100 kPa. Describe the evolution of phases and phase compositions as the temperature is gradually reduced to 70C. 12.14. Consider an ethanol(1)/ethyl acetate(2) mixture with x1 = 0.80, initially at 80C and 100 kPa. Describe the evolution of phases and phase compositions as the temperature is gradually reduced to 70C. =
