Positive deviation from ideal behaviour takes place because of

Options

A. (a) The molecular interaction between atom and `PV//nRTgt1`
B. (b) The molecular interaction between atom and `PV//nRTlt1`
C. (c) The finite size of atoms and `PV//nRTgt1`
D. (d) The finite size of atoms and `PV//nRTlt1`

Explanation

To solve the question regarding the positive deviation from ideal gas behavior, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Ideal vs. Real Gases**:
- Ideal gases follow the equation \( PV = nRT \) perfectly, while real gases do not due to intermolecular forces and the volume occupied by gas molecules.

2. **Defining Deviation**:
