Q100 · CSIR NET Chemistry, June 2011
Paper: CSIR NET June 2011 · Subject: Physical Chemistry · Chapter: Atomic and Molecular Term Symbol · Topic: Atomic And Molecular Term Symbols – General · Marks: 2 · Difficulty: Medium
The virial expansion for a real gas can be written in either of the following forms:
\[ \begin{aligned} \frac{P \bar{V}}{R T} &=1+B_{p} P+C_{p} P^{2}+\ldots \\ &=1+B_{v} V+C_{v} V^{2}+\ldots \end{aligned} \]
If $B_{0}=\alpha B$, the value of $\alpha$ would be(a)PV/RT
(b)RT/PV
(c)PV
(d)RT
Answer
Answer: D ✓ checked by 4AB · confidence high
Explanation
Equating the two virial series with P ≈ RT/V to first order gives B_V = RT·B_P, so α = RT.
