Define van't Hoff factor . How is it related to the degree of dissociation ?

Explanation

**Step-by-Step Solution:**

1. **Definition of van't Hoff Factor (i):**
The van't Hoff factor (i) is defined as the ratio of the actual number of particles in solution after dissociation to the number of formula units of the solute that were initially dissolved. It indicates how many particles a solute breaks into when it dissolves in a solvent.

Mathematically, it can be expressed as:
\[
i = \frac{\text{actual number of particles in solution}}{\text{number of formula units of solute dissolved}}
