What is Dalton's Law of Partial Pressures for a mixture of non-reacting gases?
Answer and explanation
Correct answer: C. Total pressure equals the sum of partial pressures of all individual component gases
- Step 1: John Dalton formulated that each gas in a mixture behaves independently. Step 2. The total pressure exerted by the mixture equals the algebraic sum of the partial pressures exerted by each component gas: P_total = P1 + P2 + P3 + ... Answer: Total pressure equals the sum of partial pressures of all individual component gases. Why not the others: Product of pressures is non-physical; pressure does not depend only on heaviest gas; volume squared is non-physical.
