In Vander Wall's equation `(P +(a)/(V^2))(V - b) = RT` What are the dimensions of a and b ? Here, P is pressure, V is volume, T is temperature and R is gas constant.

Explanation

To find the dimensions of \(a\) and \(b\) in the Van der Waals equation \((P + \frac{a}{V^2})(V - b) = RT\), we need to analyze the equation dimensionally.

### Step-by-Step Solution:

1. **Identify the dimensions of pressure \(P\):**
\[ [P] = \text{Pressure} = \frac{\text{Force}}{\text{Area}} = \frac{MLT^{-2}}{L^2} = ML^{-1}T^{-2} \]
