Question

Find the partial pressure of ${C O}_{2}$ , $H_{2}$ , $O_{2}$ . Total pressure = 5 atm.
$C O_{2}$ = 5 moles, $H_{2}$ = 3 moles, $O_{2}$ = 2moles:

Open in App

Solution

total moles $= (5 + 3 + 2)$ moles $= 10$ moles.

Moles of $C O_{2} = 5$ mol

$PCO2=mole fraction of CO2×$ total pressure

$= \frac{5}{10} \times 5 = 2.5$ atm

Similarly $P_{H_{2}} = \frac{3}{10} \times 5 = 1.5$ atm

$P_{O_{2}} = \frac{2}{10} \times 5 = 1$ atm
