Statement 1: If H2 and Cl2 enclosed separately in the same vessel exert pressures of 100 and 200 mm respectively, their mixture in the same vessel at the same temperature will exerts a pressure of 300 mm.
Statement 2: Dalton's law of partial pressures states that total pressure is the sum of partial pressures.
Options:
Answer:
A
Solution:
Even granting that H2 + Cl2 → 2HCl can occur, the reaction has Δ n = 0: 100 mm of H2 consumes 100 mm of Cl2 and produces 200 mm of HCl, leaving 100 mm Cl2 + 200 mm HCl = 300 mm. With no reaction the total is trivially 300 mm by Dalton's law. So the mixture exerts 300 mm either way — Statement 1 is correct and is a direct application of Statement 2 (correct statement of Dalton's law). Ans: (a).
