Chemical Reactions and Heat Lab

My hypothesis is, how does the rate of chemical reaction change by the increase of temperature?

Results:
Hot water test-20 seconds- 50 degrees C

Room temp. water test- 27 seconds- 25.1 degrees C

Cold water test- 1 minute and 56 seconds- .8 degrees C

                                           This is the chart that shows our results
                                                  of the different water temps.

My hypothesis was correct and the amount of chemical reaction does effect the temperature, because in our test the temperature was changed by the amount of chemicals added to the water test used.
