Calorimetry Question
« on: June 29, 2011, 08:43:19 pm »

With regards to drawing a heat vs time graph for a calorimeter, I know that the graph for an insulated calorimeter would be a straight line with a constant gradient; however, what would it be for a non-insulated calorimeter? Right now I'm guessing that it has an almost 'U' shaped curve, much like an exponential graph such as y = e^x.

Thanks in advance!

Not sure what graph you are referring to.

Temperature vs time for a reaction? That largely depends on the reaction rates.
Temperature vs time after a reaction has completed?
Temperature vs time during calibration with electricity?

It's pretty much for a temp vs time during calibration with electricity, I think! Hmm

Graphite's illustration for insulated container is correct.

For poorly insulated containers, see attached graph.
