For this question, we are going to look at the ion product constant for water at two temperatures and decide if the reaction, if the forward progress is endothermic or exothermic.
00:16
So the kw for water at 25 degrees c, as you know, is 1 .0 times 10 to the minus 14th.
00:26
And we are given that the kw for water at 40 degrees is a larger number, 3 .5 .5.
00:32
Point eight times 10 to the minus 14th.
00:36
Okay.
00:38
So let's take a look at our chemical equation right here, and i'm going to write the kw expression, and that is equal to the h plus concentration times the oh minus concentration.
00:54
Now, if the product is greater as is the kw at 40 degrees, it means that the products are more favored.
01:06
So at 40 degrees, the products are more favored...
