Asked by Christina
How can I tell from a graph of temperature vs. time if a reaction is endothermic or exothermic?

My final temperature was higher than my initial temperature, and my graph shows that the temperature icreases and then decreases. I thought that would make it exothermic, but don't exothermic reactions give off heat? If someone could clear this up, I would really appreciate it! Thank you.

I think you're right. Exothermic means heat is given off; therefore, T must rise.
