Question
In the van der Waals equation P = RT/(V−b) − a/V², the dimensional formula for b is the same as that for:
Correct Answer
Option B is the correct answer.
Detailed Explanation
In the term (V−b), b must have the same dimension as V (volume). So [b] = [V] = L³.
Hint
Quantities that are added or subtracted must have same dimensions.
