Why reaction between ` NaCl and AgNO_(3)` is very fast but reaction between ` H_(2) and Cl_(2)` is slow ?

Explanation

To understand why the reaction between NaCl and AgNO₃ is very fast while the reaction between H₂ and Cl₂ is slow, we can break it down into the following steps:

### Step 1: Identify the nature of the compounds involved
- **NaCl (Sodium Chloride)** and **AgNO₃ (Silver Nitrate)** are both ionic compounds. In solution, NaCl dissociates into Na⁺ and Cl⁻ ions, while AgNO₃ dissociates into Ag⁺ and NO₃⁻ ions.

### Step 2: Analyze the reaction between NaCl and AgNO₃
- When NaCl and AgNO₃ are mixed in solution, the Na⁺ and Cl⁻ ions from NaCl and the Ag⁺ and NO₃⁻ ions from AgNO₃ are present. The oppositely charged ions (Ag⁺ and Cl⁻) attract each other strongly due to electrostatic forces, leading to the immediate formation of AgCl, which is a precipitate.
