The data table below shows four different chemical reactions, the temperature change of each, and the duration of the change in temperature. Based on this data, which reaction would be classified as an exothermic reaction? Explain your answer. ALL TEMPS ARE IN CELSIUS
Reaction 1: temp change: -25 degrees; duration of temp change: 25 mins
Reaction 2: temp change: -23 degrees; duration of temp change: 15 mins
Reaction 3: temp change: -30 degrees; duration of temp change: 25 mins
Reaction 4: temp change +22 degrees; duration of temp change: 30 mins
