Question

N2 is expelled from a vessel of 5LCapacity by heating it from 27 C to 57C the fraction of N2 gas explled under condition that the pressure is Constant at 2 atm?

Answer 1

do yo have to calculate amount of gas expelled ?

Answer 2

Percentage...

Answer 3

use \[PV=nR \Delta T\] find n and then assume that initially you had one mole of it and you can find the percentage

Answer 4

your n will be around 0.04 mole

Answer 5

It wont match the answer shuld be 10%

Answer 6

hmm

Answer 7

what did you use at the place of R

Answer 8

0.0821

Answer 9

i think R= 8.314 should be used

Answer 10

but i am sure @Kryten will give the answer :) so wait

Answer 11

ok so start with this:

pV=nRT

since there is no change in amount:

n1=n2

(pV/RT)1=(pV/RT)2
now since R is an constant you can cross it out and you get
(pV/T)1 =(pV/T)2
now since there is no change in pressure or in other words it is constant you can cross it out
V1/T1 = V2/T2
now all you need to do is to use that equation to calculate how much did N2 expand and then:
V2 = ???
Vx= V2-V1
and
V(%) = Vx/V1
