NEET Chemistry Raoult's Law MCQ Question
What does Raoult's law state about the vapour pressure of a volatile component in a solution?
It is equal to the product of its mole fraction and its vapour pressure in the pure state.
It is inversely proportional to its mole fraction in the solution.
It remains constant regardless of the solution's composition.
It decreases with an increase in the mole fraction of the solute.
Correct Answer
Detailed Explanation
Raoult's law states that the vapour pressure of a volatile component in a given solution is given by the equation p_i = x_i p_i^0, where p_i^0 is the vapour pressure of the pure component. Thus, it highlights the direct relationship between vapour pressure and mole fraction.
