Step 1
This is because the process requires energy to break the bonds between water molecules and form hydronium (H+) and hydroxide (OH-) ions. Show more…

Is the self-ionization of water endothermic or exothermic? The ionization constant for water $\left(K_{w}\right)$ is $2.9 \times$ $10^{-14}$ at $40^{\circ} \mathrm{C}$ and $9.3 \times 10^{-14}$ at $60^{\circ} \mathrm{C}$

For the autoionization of water, ΔH° = 5.58 x 10^4 J. 2H2O (l) ⇌ H3O+ (aq) + OH- (aq) Kw = 1.0 x 10^-14 at 25 °C. Assuming that ΔH° is constant over the temperature range 25–100°C, calculate KW at 53 °C. (Hint: Units!) (For values in scientific notation, use "e" to represent x10^)
