JEE Advanced Model Paper 15 with solutions for online practice

Which of the following statement(s) are CORRECT?
P: At constant temperature, the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas
Q:Lowering of vapour pressure increases with increase in temperature.
R:Lowering of vapour pressure is directly proportional to mole fraction of solute. Mole fraction of solute depends upon temperature.
S: Relative lowering of vapour pressure is independent of temperature
