At a same temperature , hydrgone is more soluble in water than helium . Which of them will have a higher value of `K_(H)` and why ?

Explanation

To solve the question, we need to understand the relationship between the solubility of gases in water and the Henry's law constant (K_H). Here’s the step-by-step solution:

### Step 1: Understand Henry's Law
Henry's Law states that the amount of gas that dissolves in a liquid at a given temperature is directly proportional to the partial pressure of that gas above the liquid. The law can be expressed as:
\[ C = K_H \cdot P \]
where:
- \( C \) = concentration of the gas in the liquid (solubility)
- \( K_H \) = Henry's law constant
