Chemical Reactions and Heat Lab Investigation

The time the reaction took decreased as the temperature got warmer.  When the temperature was 50 C the time for the alka seltzer to fully dissolve was only 21.47 seconds.  But when we decreased the temperature to 24 C, the reaction took 14.86 seconds longer (36.33).  We also discovered that as we got closer to 0 C the reaction almost didn't ever finish.  At 1.3 C it took 134.5 seconds to dissolve, and it was still bubbling a little bit.  I think that this phenomenon occurs because colder atoms move less, and so that means that the alka seltzer wasn't exposed to as many H2O molecules.  When I created a graph of the temperatures and the time it took to dissolve, the graph was an exponential function with an equation of y=118.5705675*.962206596^x (Special thanks to Luke Hellum)
