Vedclass · Answer

(B) The auto-ionization of water is an endothermic process represented by the equation: $H_2O(l) ightleftharpoons H^+(aq) + OH^-(aq)$.According to Le Chatelier's principle,for an endothermic reaction,an increase in temperature shifts the equilibrium to the right.Therefore,the concentration of $H^+$ and $OH^-$ ions increases,which leads to an increase in the ionic product of water $(K_w)$.Since $90\,^{\circ}C > 25\,^{\circ}C$,the value of $K_w$ at $90\,^{\circ}C$ must be greater than $10^{-14}$.Among the given options,only $1 	imes 10^{-12}$ is greater than $10^{-14}$.

The ionic product of water at $25\,^{\circ}C$ is $10^{-14}$. The ionic product at $90\,^{\circ}C$ will be
