The freezing of aqueous 0.1 M `Na_(2)CO_(3)`, solution is less / more than 0.2 M NaOH solution.

Explanation

To determine whether the freezing point of a 0.1 M Na₂CO₃ solution is less than or more than that of a 0.2 M NaOH solution, we need to analyze the colligative properties, specifically the freezing point depression.

### Step-by-Step Solution:

1. **Understand Freezing Point Depression**:
The freezing point depression (ΔTf) is given by the formula:
\[
\Delta T_f = i \cdot K_f \cdot m
