WebNov 13, 2024 · Using the value of K b from the table, the boiling point will be raised by (0.514 K mol –1 kg) × (5.8 mol kg –1) = 3.0 K, so the boiling point will be 103° C. Freezing Point Depression The freezing point of a substance is the temperature at which the solid and liquid forms can coexist indefinitely — that is, they are in equilibrium. WebJun 25, 2014 · Acetone evaporates quickly because it has a high vapor pressure. This high vapor pressure is caused by the low intermolecular forces of attraction between its compositions. High vapor pressure also means to have a low boiling point. Next was Ethyl acetate, it evaporates faster than other organic compounds except for Acetone in the …
