Ludmilka [50]

Answer:

The correct answer is option 3.

Explanation:

H_2O\rightleftharpoons H^++OH^-

The expression of K_w is given by :

K_w=[H^+][OH^-]

K_w\propto [H^+]

K_w\propto [OH^-]

Rise in temperature will result in more dissociation of water molecules into hydrogen ions and hydroxide ions.

With an increase in concentration of hydrogen ions and hydroxide ions value of K_w will also increase.
