⇐ To index

 

Particles corresponding to three gaseous substances A, B and C, are represented by white, red and blue balls respectively. The following figures show representative portions of the three gaseous substances occupying the same volume and the same temperature.

 

 

Select the figure in which the P_B=2P_A.

	Wrong. So that this condition is met the molar fraction of B should be twice that of A. This is not true in this figure.
	Wrong. The molar fraction of B should be twice that of A. In this figure X B=1.5XA.
	Right. In this figure XB= 2XA. Therefore PB= 2 PA
	Wrong. In this figure XB=2.75XA
