Question

What does Raoult's law state?

Answer 1

1. According to Raoult's law, at any specific temperature, the partial pressure of the component in the vapor phase is equal to the multiplication of the mole fraction of the solvent and the partial pressure of the pure component.
2. The mathematical expression of Raoult's law is, ${\mathrm{p}}_{\mathrm{i}}={{\mathrm{p}}_{\mathrm{i}}}^0\times {\mathrm{X}}_{\mathrm{o}}$, Here, $p_i$ is the partial pressure of the component, ${p_i}^o$is the vapor pressure of the pure component, and $X_o$is the mole fraction of solvent.
3. Raoult's law is applicable to ideal solutions.
