States of Matter - Result Question 18
18. Positive deviation from ideal behaviour takes place because of $(2003,1 M)$
(a) molecular interaction between atom and $p V / n R T>1$
(b) molecular interaction between atom and $p V / n R T<1$
(c) finite size of atoms and $p V / n R T>1$
(d) finite size of atoms and $p V / n R T<1$
Show Answer
Answer:
Correct Answer: 18. (a)
Solution:
Positive deviation corresponds to $Z>1$
$\because \quad Z=\dfrac{p V}{n R T}$, for positive deviation, $\dfrac{p V}{n R T}>1$.
