WebApr 23, 2024 · Boiling point elevation equation. A colligative property depending on the amount of particles in a solution. Delta T of solvent = Boiling point constant (given) ( Molality) Van t hoff factor (Number of particles in solution) molality = moles of solute / Kg of solvent = 9.19 moles of C2H6O2 / .8 Kg of water = 11.5 mols/ Kg. WebSo when water boils at 100 C at 1 atm, this means that only at 100 C does the vapour pressure of the water overcome the external vapour pressure. If you increase the external pressure to 2 atm, the water requires more energy to be able to overcome this pressure, therefore boiling point increases. this is how it works.
