Question
The inversion temperature of hydrogen is (given van der Waal′s constants a and b are 0.244 atmL2mol-2 and 1.027 L mol-1 respectively)
Options
A.440
B.220
C.110
D.330
Solution
Gases become cooler during joule Thomson′s expansion only if they are below acertain temperature known as inversion temperature (Ti). The inversion temperature is characteristic of each gas is given by
Ti =
Where R is gas constant
Given a = 0.244 atmL2mol-2
b = 0.027 L mol-1
R = 0.0821 L atmdeg-1 mol-1
∴ Ti =
= 220K
Ti =
Where R is gas constant
Given a = 0.244 atmL2mol-2
b = 0.027 L mol-1
R = 0.0821 L atmdeg-1 mol-1
∴ Ti =
= 220KCreate a free account to view solution
