## 1 Answer

Inversion Temperature is $\large\frac{2a}{Rb}$
The Joule-Thomson effect is obeyed by a gaseous system only when its temperature is below a characteristic value. The characteristic temperature below which a gas expands adiabatically into a region of low pressure through a porous plug with a fall in temperature is called as inversion temperature (Ti). Ti is characteristic of a gas and it is related to the Vanderwaal's constant a' and b', 2a Ti = 2a / Rb
Hence c is the correct answer.
