Question

which of the 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

Answer 1

Cl2 and so2 is the right answer

Answer 2

The gases $\mathrm{Cl}_{2} \text { and } \mathrm{SO}_{2}$ do not obey ‘Dalton’s law’ of ‘partial pressure’.

Option: (a)

Explanation:

Dalton’s law states that,

• The ‘total pressure’ applied by a ‘gas mixture’ is always equals to sum of the ‘partial pressures’ present in the component gases of that respective gas mixture. It can be ‘expressed’ as,

         $\mathrm{P}=\mathrm{P}_{1}+\mathrm{P}_{2}+\mathrm{P}_{3}+\ldots \ldots$

• ‘Partial pressure’ can be formulated as below,

         $\text { Partial pressure }=(\text { Volume of a gas / Total volume) } \times\text { Total pressure applied }$

• Dalton’s law of the ‘partial pressures’ has not been applied in the provided gases like $\mathrm{CO}+\mathrm{O}_{2}, \mathrm{NO}+\mathrm{Cl}$, and so on.
