An equimolar ternary mixture of acetone, n-butane, and ammonia at 1 MPa is to be flashed. List the known variables, unknown variables, and constraining equations to solve each of the cases below. Assume MAB solution thermodynamics and write the flash equations in terms of K-ratios, with the equations for calculating K-ratios written separately. (Hint: Remember to include the activity coefficients and how to calculate them.

(a) Bubble temperature (b) Dew temperature (c) Flash temperature at 25mol% vapor (d) Raised to midway between the bubble and dew temperatures, then adiabatically flashed.
