1 mole of $N_{2}O_{4}(g)$ at 300 K is kept in a closed container under 1 atm. It is heated to 600 K when 20% by mass of $N_{2}O_{4}(g)$ decomposes to $NO_{2}(g)$. The resultant pressure is

(b)
$N_{2}O_{4} ightleftharpoons 2NO_{2}$
Initial 1 mol 0
At eqm 1-0.20 0.40 mol
$pV = nRT$
$1 	imes V = 1 	imes R 	imes 300$ …(i)
$p 	imes V = 1.2 	imes R 	imes 600$ …(ii)
On dividing (ii) by (i)
$p = 2.4$ atm
