Q. Raoult's law states that the partial vapor pressure of a component in a solution is:

राउल्ट का नियम बताता है कि किसी घोल में किसी घटक का आंशिक वाष्प दबाव है:

A
Equal to its mole fraction times its vapor pressure in pure state
शुद्ध अवस्था में इसके मोल अंश के गुणा इसके वाष्प दबाव के बराबर
B
Equal to its mass fraction times its vapor pressure in pure state
शुद्ध अवस्था में इसके द्रव्यमान अंश के गुणा इसके वाष्प दबाव के बराबर
C
Independent of its mole fraction
इसके मोल अंश से स्वतंत्र
D
Equal to the vapor pressure of the pure component
शुद्ध घटक के वाष्प दबाव के बराबर

Explanation

Raoult’s law states:

PA=XA×PA0

where PA is the partial vapor pressure of component A in the solution, XA is its mole fraction, and PA0 is the vapor pressure of the pure component A.

It depends on mole fraction, not mass fraction or other parameters.
