A vessel of volume 10 litres holds 1.4 g of nitrogen at 2000 K , and 50\% of the molecules are dissociated into atoms. Find the pressure in atm (two decimals).

Answer:

1.23

Solution:

Particles = $\frac{1.4}{28} (1 + 0.5) = 0.075$ mol.

$P = \frac{n RT}{V} = \frac{0.075 \times 8.314 \times 2000}{1 0 ^{- 2}}$ Pa

= $1.23$ atm.
