Question
A vessel of volume 5 litre contains 1.4 g of nitrogen at a temperature 1800 K. The pressure of the gas if 30% of its molecules are dissociated into atoms at this temperature is :
Options
A.4.05 atm
B.2.025 atm
C.3.84 atm
D.1.92 atm
Solution
N2 → 2N
at t = 0
0
at t = tf
-x 2x
but, x = 30% of
Final number of mole =
- x + 2x = 
+ x = 
∴ P =
= 1.92 atm.
