AIIMS 2008 Chemistry Dalton's Law of Partial Pressures Assertion Reason Question
Assertion : If H₂ and Cl₂ enclosed separately in the same vessel exert pressure of 100 and 200 mm respectively, their mixture in the same vessel at the same temperature will exert a pressure of 300 mm.
Reason: Dalton's law of partial pressures states that total pressure is the sum of partial pressures.
If both assertion and reason are true and reason is the correct explanation of assertion
If both assertion and reason are true but reason is not the correct explanation of assertion
If assertion is true but reason is false
If both assertion and reason are false
Correct Answer
Detailed Explanation
H2 and Cl2 react chemically. Hence Dalton’s law is not applicable. Dalton’s law states that “at a given temperature, the total pressure exerted by two or more non-reacting gases occupying a definite volume is equal to the sum of the partial pressures of the component gases.”
