How to calculate theoretical boiling point
WebDetermine the three operating lines and draw them on the x-y diagram Using the rectifying operating line and the equilibrium curve draw steps from the distillate composition to the feed point Count the number of steps. Each one equals an equilbrium or theoretical stage Using the stripping operating line and the equilibrium curve Web7 sep. 2024 · The rather simple equation for determining boiling point of a solution: delta T = mKb. Delta T refers to the boiling-point elevation, or how much greater the solution’s boiling point is than that of the pure solvent. The units are degrees Celsius. Kb is the molal boiling-point elevation constant.
