I would guess you’ve never read a book by the title of “Kelvin 506”. Interestingly, it has been proposed that this is the temperature at which paper experiences auto-ignition – it spontaneously combusts!
Why It Matters
- The temperature matters a lot for some reactions (Have you ever tried to cook an egg at room temperature?). When the products of a reaction are not favored or when a reaction cannot occur, the reaction is deemed non-spontaneous. Changing the temperature can render processes spontaneous (note: this does not always mean you should increase the temperature; some processes are only spontaneous at lower temperature – think freezing water.)

Can You Apply It?
With the links below, learn more about how temperature affects the spontaneity of a reaction. Then answer the following questions.
- The sign of (positive or negative) determines if a reaction is spontaneous or non-spontaneous. Since it is possible for to be negative at all possible temperatures. When is this the case?
- Not all paper auto-ignites at 506 K. Please provide some reasons that this might be the case.
