Question

the Vander Waal constant a and b for a gas are 0.21 and 0.017 in dm³ atm units . calculate the inversion temperature of the gas.​

Answer 1

Answer:

220k ..................

Answer 2

Gases become cooler during Joule Thomson's expansion only if they are below a certain temperature known as inversion temperature (T

i

).

The inversion temperature is characteristic of each gas and is given by T

i

=

bR

2a

where R is gas constant

Given:

a=0.244 atm L
