. Which of the following mixtures of gases does not obey
Dalton's law of partial pressure?
(a) Cl2 and SO2
(b) CO2 and He
(c) O2 and CO2
(d) N2 and O2
Best Answer
Correct Option is : (a)
Dalton’s law of partial pressures is a gas law which states that the total pressure exerted by a mixture of gases is equal to the sum of the partial pressures exerted by each individual gas in the mixture.
Condition: The mixture of the gases should be non-reacting,
But,
Cl2+SO2⟶ Sunlight SO2Cl2(Sulphuryl chloride)
As Cl2 and SO2 reacts to form SO2Cl2 so this law is not obeyed in the given case.
