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

Answer:

2.40

Solution:

$\underset{\underset{1 - 0.2}{1}}{N_{2} O_{4}} \leftrightarrow \underset{\underset{0.4}{0}}{2N O_{2}}$

$= 0.8$

Number of moles at 300 K = 1

No. of moles at 600 K = 0.8 + 0.4 = 1.2

V is constant

$\frac{P_{2}}{P_{1}} = \frac{n_{2} T_{2}}{n_{1} T_{1}}$

$\frac{P_{2}}{1} = \frac{1.2 \times 600}{1 \times 300} = 2.4 a t m$
