Answers
1) B 2) both a and c
The answer is celsius
answer : (a) volume of the gas = 8.67 × [tex]10^{-3}[/tex] l
(b) second virial coefficient b = -1.21226 l/mole
solution : given, t = 300k
p = 20atm
z = 0.86
n = 8.2 mmoles = 8.2 × [tex]10^{-3}[/tex] moles
r = 0.082 l atm/k/mol
find, (a) volume of gas and (b) second virial coefficient b at 300k.
formula used : [tex]z=\frac{pv}{nrt}[/tex]
and [tex]z=1+\frac{b}{v}[/tex]
(a) [tex]z=\frac{pv}{nrt}[/tex]
[tex]v=\frac{znrt}{p}[/tex]
= [tex]\frac{0.86\times 8.2\times[tex]10^{-3}[/tex]\times 0.082\times 300}{20}[/tex]
= 8.67 × [tex]10^{-3}[/tex] l
(b) [tex]z=1+\frac{b}{v}[/tex]
[tex]b=(z-1)v[/tex]
= (0.00867-1) × 8.659
= - 8.5839 l/mole
