Question

The inversion temperature for a van der Waals gas is given by:

• A. ${{T}_{i}}=\frac{2a}{Rb}$
• B. ${{T}_{i}}=\frac{a}{Rb}$
• C. ${{T}_{i}}=\frac{a}{2Rb}$
• D. ${{T}_{i}}=0.5\,{{T}_{Boyle}}$

Answer 1

Answer: (A)

${{T}_{i}}=\frac{2a}{Rb}$

Answer 2

Inversion temperature of a van der Waals gas is given by ${{T}_{i}}=\frac{2a}{Rb}=2{{T}_{b}}$ (where ${{T}_{b}}=$ Boyle temperature)
