Correct option is B
Dalton’s Law of Partial Pressures states that in a mixture of non-reacting gases, the total pressure exerted by the mixture is equal to the
sum of the partial pressures of each individual gas. Mathematically,
Ptotal = P1+P2+P3+⋯+Pn
where:
· Ptotal = total pressure of the gas mixture
· P1, P2, P3,…,Pn = partial pressures of individual gases
Each gas in the mixture behaves as if it alone occupies the entire volume at the same temperature. Dalton’s law is applicable under the assumptions that the gases do not react chemically and behave as
ideal gases.
