at 27°c a closed vessel contains equal mass of he ,ch4 And so2 exerts a pressure of 29 mm And partial pressure of he ,ch4 And so2 are p1 ,p2 And p3 which is correct
p3>p2>p1
p1>p2>p3
p1>p3>p2
p2>p3>p1

Partial pressure ∝ Mole fraction
Since weights of gases are equal, gas with lower molecular weight will have higher mole fraction and vice versa.
The higher the value of mole fraction, the more is the partial pressure.
The order of molecular weight: M
He <M CH 4 <M SO 2
Therefore, the order of partial pressure: P 1 >P 2 >P 3
Hence, the correct answer is option B
