could u explain this question?
Kw comes from the autoionization of water which is endothermic process.
Heat + 2 H₂O ⇌ H₃O⁺ + OH⁻
Kw is temperature-dependent because the autoionization is an endothermic process:
• If temperature increases → equilibrium shifts right (Le Châtelier's principle) → [H3O+][H₃O⁺][H3O+] and [OH−][OH⁻][OH−] both increase → Kw increases.
• If temperature decreases → equilibrium shifts left → [H3O+][H₃O⁺][H3O+] and [OH−][OH⁻][OH−] both decrease → Kw decreases.
Now pick up your answer.
ohhh okay then it will be d
