A vessel of volume , `V = 5.0` litre contains `1.4 g` of nitrogen at a temperature `T = 1800 K`. Find the pressure of the gas if `30%` of its molecules are dissociated into atoms at this temperature.

A

`0.54xx10^(5)N//m^(2)`

B

`1,94xx10^(5) N//m^(2)`

C

`2.62xx10^(5)N//m^(2)`

D

`3.75xx10^(5)N//m^(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
`P=(mu)/(M)(RT)/(V), (P_(1))/(P_(2))-(mu_(2))/(mu_(1))+mu_(2)`
