A mixture containing 35 mole% propane and 65 mole% ethane exists at 25 atm. A. Assuming that the mixture is ideal, determine the temperature (°C) when the first bubble of vapor is formed. B. What is the composition of this first bubble of vapor? C. What temperature must be applied to vaporize one-half of the liquid (on a molar basis)?
