Correct Answer is A: <span> The vapor pressure of a pure solvent is higher than that of a solution containing that solvent.
Reason According to Raoult's Law states that v</span><span>apor pressure of each component in the solution is equal to the vapor pressure of the pure component multiplied by its mole fraction. It is mathematically expressed as P = X </span> where, P = vapor pressure of solution X = mole fraction of solute P^{0} [/tex] = vapor pressure of pure component
Raoult's law states That the vapor pressure of a pure solvent is higher than that of a solution containing that solvent. This is <span>a </span>law<span> of thermodynamics established by French chemist François-Marie </span>Raoultin in 1887. This shows that <span> partial vapor pressure is equal to the vapour pressure.</span>
