Question

Dalton's law of partial pressures is applicable to which one of the following systems ?

• A. $CO+H_2$
• B. $H_2+Cl_2$
• C. $NO+O_2$
• D. $NH_3 +HCl$

Answer 1

Answer: (A)

$CO+H_2$

Answer 2

When a mixture of two or more non-reacting gases are enclosed in a container then the total pressure exerted by the gaseous mixture is equal to the sum of partial pressure of the components in the mixture.
eg, ${CO + H_2}$ are non-reacting gases. Hence,
Dalton's law of partial pressure is applicable to this system.

So, the correct answer is (A): ${CO + H_2}$
