Raoul't law is not valid in
For very dilute solution solvent obey Raoult's law and solute also obey the same
The solubility of gas increase as temp decreases
The greater the pressure of gas greater the solubility
Non ideal solution does not obey Raoult's law
It is true that for very dilute solution ; solvent obey's Raoult's law but for solute obey's Henry's law.
