Answer 1

robot law states that at a given temperature for a solution of volatile liquids the partial vapour pressure of each component in a solution is equals to the product of vapour pressure of pure component and its mole fraction

I hope it will help you

Answer 2

HELLO THERE!

Here's the statement of Raoult's Law:

“The partial vapour pressure of any component in the solution is directly proportional to its mole fraction”.

$P_{A} = kX_{A}$

Where, $P_{A}$  =  Partial vapour pressure of A

.

$X_{A}$  =   Mole fraction of A in the solution

.

For pure liquids,

$X_{A} = 1</p><p>$

Then,

$K = P^{0}_{A}$

Where $P^{0}_{A}$  is the vapour pressure of component A in pure state

.

Hence, $P_{A}  = X_{A}P^{0}_{A}$  

Similarly, for component B, we have,

$P_{B} = X_{B}P^{0}_{A}</p><p>$

THANKS!
