The Table below shows the temperature-composition data for mixtures of ethanol (C2H5OH) and 2-methyl-1-propanol (C4H10O) at 1atm. Ethanol is more volatile and its mole fractions
The Table below shows the temperature-composition data for mixtures of ethanol (C2H5OH) and 2-methyl-1-propanol (C4H10O) at 1atm. Ethanol is more volatile and its mole fractions are given in the Table. A liquid mixture at 56C that is 45 mole % ethanol, and is a total of 320 moles, is placed in an evacuated, closed vessel. The mixture is heated until 60% is vapor and the system is allowed to attain equilibrium at 1atm and the new temperature. Plot the data and determine the followings: a. The final temperature of the mixture b. The final vapor and liquid compositions c. The temperature at which the first bubble appeared and the composition of the bubble d. The amount of the mixture (in moles) that will be liquid if the system temperature is maintained at 100C
