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 $NO_{2} (g)$ . The resultant pressure is

Options:

Answer:

Solution:

N₂O₄ ⇌ 2NO₂

At equilibrium, $1 - 0.2$ $0.4$

moles moles

At $300 K$ , $1 \times V = 1 \times R \times 300 \dots (1)$

At $600 K$ , $P \times V = (1.2) \times R \times 600 \dots (2)$

Dividing equation (2) by equation (1), we get:

$P = 2.4 a t m$
