Which of the following formulas represents Raoult's law for a solution containing non-volatile solute? |
$P_{\text{solute}} = P^\circ_{\text{solute}} \cdot \chi_{\text{solute}}$ $P = K_{\text{H}} \cdot \chi$ $P_{\text{Total}} = P_{\text{solvent}}$ $P_{\text{Total}} = P^\circ_{\text{solvent}} \cdot \chi_{\text{solvent}}$ |
$P_{\text{Total}} = P^\circ_{\text{solvent}} \cdot \chi_{\text{solvent}}$ |
The correct answer is Option (4) → $P_{\text{Total}} = P^\circ_{\text{solvent}} \cdot \chi_{\text{solvent}}$ ## According to Raoult's law, the vapour pressure of a solution of a non-volatile solute is equal to the vapour pressure of the pure solvent at that temperature multiplied by its mole fraction. |
