Answer:
The Van der Waals equation of state for some gases can be expressed as: (P+aV2)(V−b)=RT, where P is the pressure, V is the molar volume, and T is the absolute temperature of the given sample of gas. Hence, the option (A) is the correct answer.
Explanation:A
[ML5T−2]
B
[ML−1T−2]
C
[L3]
D
[L6]
Answer
A
Solution
aV2 is dimensionally equal to P
a(L3)2=[M1L−1T−2]⇒a=[M1L5T−2]
