The inversion temperature

T_i({~K})

of hydrogen is (given van der Waal's constants

a

and

b

are

0.244 {~atm} {~L} {~mol}^{-2}

and

0.027 {Lmol}^{-1}

respectively)

View answer and explanation

Correct option: B

220

Option B (220) is correct because the inversion temperature is calculated using the formula

T_i = \frac{{2a}}{{Rb}}

, where a and b are van der Waals constants.
