Statement (A): Daltons law of partial pressures states that total pressure is the sum of partial pressures.

Statement (B) : Daltons law of partial pressure is applicable for non-reacting gases.

Statement (C) : If ${\mathrm{H}}_2$ and  ${\mathrm{Cl}}_2$enclosed separately in the same vessel exert pressures of 100 an 200 mm

A) According to Dalton’s law of partial pressures “Total pressure exerted by a gaseous

mixture is equal to the sum of partial pressure of each component of mixture”.

B) Daltons law of partial pressure is applicable for non-reacting gases

${\mathrm{H}}_2\& {\mathrm{Cl}}_2$ react to give HCl. They, the pressure is not equal to 300 mm.
