A gaseous mixture contains 2 moles of A and 3 moles of B. Total pressure of the mixture is 5 atm. The partial pressures of A and B are respectively. (AFMC 2010)
A.2 atm and 4 atm
B.2 atm and 3 atm✓ Correct
C.3 atm and 2 atm (d) 6 atm and 2 atm
Explanation
Mole fraction of 2 2 0.4 2 3 5 A Mole fraction of 3 3 0.6 2 3 5 B Partial pressure of gas A mole fraction of A = 5 × 0.4 =2 atm total P x Partial pressure of gas B mole fraction of B = 5 × 0.6 =3 atm total P x
