When solid NH_(4)NO_(3) is dissolved in water at 25^(@)C , the temperature of the solution decreases. What is true about the signs of DeltaH and DeltaS for this process?

STATEMENT-1 : For solution of volatile liquids, the partial vapour pressure of each component in the solution is directly proportional to its mole fraction. STATEMENT-2 : Always there will be lowering of vapour pressure on addition of non-volatile solute to a solvent. STATEMENT-3 : If there is dissociation of non-volatile then the V.P. of solution increases.
