At room temperature following traction goes to completion
$2 A B (g) + B_{2} (g) \to 2 A B_{2} (s)$
$A B_{2}$ is solid with negligble vapour pressure below $0^{\circ} C$ . At 300 K, the AB in the smaller flask exerts a pressure of 3 atm and in the larger flask $B_{2}$ exerts a pressure of 1 atm at 400 K when they are separated out by a close valve, The gases are mixed by opening the stop cock and after the end of the reaction the flask are cooled to 250 K

The final pressure is :
