JEE Advanced 2014 Paper 1 Offline Chemistry - Gaseous State Question 12 English

An ideal gas in thermally insulated vessel at internal pressure = p₁, volume = V₁ and absolute temperature = T₁ expands irreversibly against zero external pressure, as shown in the diagram.

The final internal pressure, volume and absolute temperature of the gas are p₂, V₂ and T₂, respectively. For this expansion

q = 0

T₂ = T₁

p₂V₂ = p₁V₁

p₂V$$_2^\gamma $$ = p₁$$_1^\gamma $$

The given graph represents the variation of Z (compressibility factor $=\mathrm{PV} / n \mathrm{RT}$ ) versus P , for three real gases $\mathrm{A}, \mathrm{B}$ and C . Identify the only incorrect statement.

IIT-JEE 2006 Chemistry - Gaseous State Question 2 English

For the gas A, $a=0$ and its dependence on P is linear at all pressure.

For the gas $\mathrm{B}, b=0$ and its dependence on P is linear at all pressure.

For the gas C , which is typical real gas for which neither $a=0$ nor $b=0$. By knowing the minima and the point of intersection, with $Z=1, a$ and $b$ can be calculated.

At high pressure, the slope is positive for all real gases.
