Ответ:
Reason
According to Raoult's Law states that vapor 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
where, P = vapor pressure of solution
X = mole fraction of solute
P^{0} [/tex] = vapor pressure of pure component
Here X is always less than one (in solutions)
∴ P < P^{0} [/tex]
