Question

1. would you use reaction 1 or reaction 2 if you were constructing a device that became warm to the touch? explain your answer.

Explanation:

An exothermic reaction releases heat, which would make a device warm to the touch. Reaction 2 shows a decrease in energy (as per the graph's trend), indicating heat release (exothermic). Reaction 1 shows an increase in energy (endothermic, absorbing heat).

Answer:

Reaction 2. Because it is exothermic (releases heat), making the device warm.
