Question

Consider the following statement $P{V}_m=RT(1+\frac{B}{V_m}+\frac{C}{V_m^2}+...)$,then $V_m$

• A. Is independent of temperature
• B. Is equal to $\frac{RT}{P}$ at Boyle's temperature
• C. Has the dimension of molarity
• D. None of these

Answer 1

The correct option is B Is equal to $\frac{RT}{P}$ at Boyle's temperature

At Boyle's temperature real gas behaves as ideal gas over an appreciable range of pressure, so$P{V}_m=RT$
$\therefore V_m=\frac{RT}{P}$
