Question

Helloall,

There is a question thatstates: When two pure liquids, A and B, are mixed, the temperatureof the solution increases. Which statement is NOTtrue? The answer was: The vapor pressure of the solution is lessthan both the vapor pressure of pure A and pure B in solution.

^^ I did not understandthis at all.

It says a truestatement is that the reaction is exothermic and I did notunderstand why this is? May someone explain this statement as well?

May someone explain insimplified terms what Raoult's law really mean? I am soconfused. Examples to compare to would be great, ifpossible.

I will rate alifesaver.

Explanation / Answer

    Roult s law states that when a non voltilesolvent is added to pure solvent then the vapor pressureof the solution     is lowered than the pure solvent vaporpressure .     So based on this statement when A & Bare mixed together form a new solution which is having lowvapor pressure     than thier individual pure solvents of Aand B.
