MHT CET 2024 Chemistry question

If is partial pressure of a gas and is it's mole fraction in a mixture, then correct relation between and is

(A)
(B)Correct
(C)
(D)

Answer: (B)

Solution

By Dalton's law of partial pressures, the partial pressure of a component in a gas mixture is the product of its mole fraction and the total pressure: . Rearranging gives , which is option (B). In (A), (C)
