Consider a one-component system with a liquid phase and a gas phase. a. Draw schematically the Gibbs energy of the two phases as a function of temperature under a given constant pressure (2pt). Label the curves (1pt). Discuss the fundamentals behind your choice of the slopes of the curves. (2pt) Are the curves straight lines? (2pt) b. Draw schematically the Gibbs energy of the two phases as a function of negative pressure under a given temperature and repeat the discussion from part 1. (3pt)
