The ionic product of water is ` 0.11 xx 10 ^(-14) ` at 273 K. ` 1.0 xx 10 ^(-14) at 298 K and 5.1 xx 10 ^(-14) at 373 K ` Deduce from this data whether the ionisation of water to hydrogen and hydrooxide ions is exothermic or endothermic.

Explanation

To determine whether the ionization of water into hydrogen ions (H⁺) and hydroxide ions (OH⁻) is exothermic or endothermic based on the provided ionic product of water at different temperatures, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Ionization of Water**:
The ionization of water can be represented by the equation:
\[
\text{H}_2\text{O} \rightleftharpoons \text{H}^+ + \text{OH}^-
