The larger the molecular size..........should be the value of b.

Explanation

To solve the question "The larger the molecular size..........should be the value of b," we can follow these steps:

### Step 1: Understand the Context
The question relates to the Van der Waals equation, which is used to describe the behavior of real gases. In this equation, 'b' represents the volume occupied by one mole of gas particles.

### Step 2: Recall the Van der Waals Equation
The Van der Waals equation is given by:
\[ P + \frac{aN^2}{V^2} (V - Nb) = NRT \]
