Two moles of `N_2` gas in a 50 L vessel at STP shows

A

positive deviation

B

negative deviation

C

ideal gas behaviour

D

first positive then negative deviation

Text Solution

Verified by Experts

The correct Answer is:
A
`Z= (PV)/(nRT)`
at STP , P=1 atm ,T = 273K
Given `V=50 L , n=2 ml , R= 0.0821 L "atm K"^(-1) " mol"^(-1)`
`Z= (1 xx 50)/( 2 xx 0.0821 xx 273) = 1.1`
Since `Z gt 1`, the gas shows positive deviation from ideal behaviour.
