The ionic product of water is 0∙11 x 10-14 at 273 K, 1 x 10-14 at 29

1.	The ionic product of water is 0∙11 x 10-14 at 273 K, 1 x 10-14 at 298 K and 7∙5 x 10-14 at 373K. Deduce from this data whether the ionization of water to hydrogen and hydroxide ion is exothermic or endothermic?
Answer» K_ω = (H3O⁺)(OH⁻) According to the data, the value of K_ω is increasing with temperature. Therefore, according to Le-Chatelier's principle, the ionisation of water is endothermic.

Answer»

K_ω = (H3O⁺)(OH⁻)

According to the data, the value of K_ω is increasing with temperature. Therefore, according to Le-Chatelier's principle, the ionisation of water is endothermic.
