A) Henry's law
B) Raoult's law
C) Ostwald's law
D) Arrhenius's law
Correct Answer: B
Solution :
The relative lowering of vapour pressure is equal to the mole fraction of the solute. This law is called Raoult's law. Relative lowering of vapour pressure = mole fraction of the solute\[\frac{{{P}^{o}}-{{P}_{s}}}{{{P}^{o}}}=\frac{n}{n+N}\]You need to login to perform this action.
