analyze exothermic and endothermic graphs

1. the temperature

after the reaction is greater than the temperature
before the reaction.

1. the reaction release thermal energy.
2. this is an absorb reaction.

Explanation:

Step1: Recall exothermic and endothermic reaction concepts

Exothermic reactions release heat, endothermic absorb heat.

Step2: Analyze temperature change

If temperature after reaction > before, heat is released.

Step3: Identify reaction type

Since heat is released, it's an exothermic reaction.

Answer:

1. After; Before
2. Release
3. Exothermic
