Question

The value of Kw increases with increasing temperature. Is the 
autoionization of water endothermic or exothermic?

Accepted Answer

Hey everyone today, we're being asked to classify the auto ionization of water as either an XR thermic or endo thermic process. Now, given in the question, we are told that the ionization constant of water or K. W. Is directly proportional to the temperature, rather the change in temperature. So if K W. Or sorry, if the temperature increases, then that means that the KW also increases similarly, if temperature decreases, then the K W will also decrease as such. This means that if temperature increases, if the change in temperature increases, put that over here, then that means that more products are formed, more products are formed, which means that heat would be a reactant in the auto ionization of water. And let's just take a look at how that would look. The auto ionization of water, what look like. So where heat or the change in heat would be a reactant as adding more of it according to the chandeliers principle would also increase the amount of products formed which in this case our hydro ni um and hydroxide. Therefore, since heat is a reactant, say reactant, That means the auto ionization of water. The auto ionization of water is an endo thermic process is endo thermic thermic, sorry, let me write that a little neater. Is endo thermic. I hope this helps. And I look forward to seeing you in the next one
