NEET 2022 Chemistry Dalton’s Law of Partial Pressure MCQ Question
Which one is NOT correct mathematical equation for Dalton’s Law of partial pressure? Here p = total pressure of gaseous mixture
pᵢ = xᵢp, where pᵢ = partial pressure of ith gas, xᵢ = mole fraction of ith gas in gaseous mixture
pᵢ = xᵢpᵢ⁰, where xᵢ = mole fraction of ith gas in gaseous mixture, pᵢ⁰ = pressure of ith gas in pure state
p = p₁ + p₂ + p₃
p = n₁ RT/V + n₂ RT/V + n₃ RT/V
Correct Answer
Detailed Explanation
Dalton’s Law states that the total pressure of a gas mixture is the sum of the partial pressures of each individual gas. Option B incorrectly uses the pure state pressure instead of partial pressure.
