(a) Define Kohlraush’s law.

Explanation

**Step-by-Step Solution:**

1. **Understanding Molar Conductivity:**
- Molar conductivity (Λ) is defined as the conductivity of an electrolyte solution divided by its molar concentration. It measures how well an electrolyte conducts electricity in solution.

2. **Infinite Dilution:**
- Infinite dilution refers to the condition where the concentration of the electrolyte approaches zero. Under this condition, the interactions between ions are minimal, allowing us to study their individual contributions to conductivity.
