1 CHEN 3320: ChE Thermodynamics Department of Chemical and Biological Engineering Fall 2010 John L. Falconer ——————————————————————————————————————— Assignment #7 due Friday, October 22, 2010 1) E-L, 9.1 2) (a) Calculate the dew point temperature for a mixture that is 30% n-pentane and 70% n-butane at a pressure of 15 bar. (b) Determine the temperature to completely condense the vapor, and the composition of the last drop of vapor. 3) Proteins are long chain polymers in which amino acids are linked by bond between carbon atoms and nitrogen atoms. The polymer molecule folds back onto itself to form molecular bonds (columbic, hydrogen, and van der Waals bonds). Multiple foldings of the structure take place. Use the Gibbs energy to explain why proteins are not stable at high temperatures. 4) The following equation represents the enthalpy of a mixture of water and sulfuric acid. Calculate the partial molar enthalpies for water and sulfuric acid for a mole fraction of
