Question

For a mixture of gases, Dalton's law of partial pressures states:
  1. A
    P_total = ΣP_i (sum of partial pressures of each component)
    Correct
  2. B
    P_total = P₁ × P₂ × P₃
  3. C
    P_total = P_max
  4. D
    P_total = P_avg

Correct answer

P_total = ΣP_i (sum of partial pressures of each component)

Explanation

Dalton's Law: total pressure of a non-reacting gas mixture = sum of partial pressures. Pᵢ = xᵢ × P_total, where xᵢ = mole fraction of component i.
