Question 1

What is a Raoult's Law?

Accepted Answer

Raoult's Law states that the partial vapour pressure of a volatile component in an ideal solution is proportional to its mole fraction and pure component vapour pressure. P_solution = x_solvent × P°_solvent.

Question 2

How does the Raoult's Law work?

Accepted Answer

P_solution = x_solvent × P°_pure Then: x_solvent = moles solvent / total moles Then: Vapour pressure lowering: ΔP = x_solute × P°_pure Then: Basis for boiling point elevation and freezing point depression.

Question 3

Can you give an example of how to use the Raoult's Law?

Accepted Answer

Example: Input Benzene P°=96 mmHg · xbenzene=0.7 in toluene solution gives a result of P_benzene = 0.7 × 96 = 67.2 mmHg (Raoult's law for ideal mixtures).
