State Raoult's law for a solution containing volatile components. Write two characteristics of the solution which obeys Raoult's law at all concentrations.

Explanation

**Step-by-Step Solution:**

1. **State Raoult's Law:**
Raoult's Law states that for a solution containing volatile components, the vapor pressure of each component in the solution is directly proportional to its mole fraction in the solution. Mathematically, this can be expressed as:
\[ P_A = P_{A}^{0} \cdot X_A \]
\[
