Question
One of the two ideal gases has a molar volume double the second one at the same temperature, Calculate the ration of their pressure.
- 4:1
- 2:1
- 1:2
- 3:5
The correct answer is: 1:2
Using the ideal gas equation,
PV = nRT
Here, Va : Vb = 2 : 1 and Temperature is constant.
From the ideal gas equation, P ∝ 1/V. Therefore we have,
Pa : Pb = Vb : Va
Pa : Pb = 2 : 1
