Example 4
easyA reaction mixture causes the beaker and surrounding air to become warmer. Is the reaction exothermic or endothermic? Explain.
Solution
- 1 If the surroundings get warmer, the reaction must be releasing energy to the surroundings.
- 2 A reaction that releases heat is exothermic.
Answer
Exothermic.
Exothermic reactions transfer energy from the system to the surroundings. That released energy often appears as a rise in temperature of the reaction container or nearby air.
About Exothermic Reaction
A chemical reaction that releases energy (usually as heat or light) to the surroundings, resulting in an increase in surrounding temperature and a negative enthalpy.
