During the adsorption of krypton on activated charcoal at low temperature

Options

A. `Delta H gt 0 and DeltaS lt 0`
B. `DeltaH lt 0 and Delta S lt 0`
C. `Delta H gt 0 and Delta S gt 0`
D. `Delta S lt 0 and Delta S gt 0`

Explanation

To determine the entropy change during the adsorption of krypton on activated charcoal at low temperature, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Adsorption**:
- Adsorption is the process where gas molecules (in this case, krypton) adhere to the surface of a solid (activated charcoal). The gas molecules form physical bonds with the surface of the adsorbent.

2. **Nature of Krypton**:
