Q: Which of the following statements is true about an exothermic reaction?
Solution:
An exothermic reaction releases heat, resulting in a negative enthalpy change.
Steps: 4
Show Steps
Step 1: Understand what an exothermic reaction is. It is a type of chemical reaction that releases heat.
Step 2: Know that when heat is released, the temperature of the surroundings increases.
Step 3: Learn about enthalpy change, which is a measure of heat content in a system.
Step 4: In an exothermic reaction, the enthalpy change is negative because the system loses heat to the surroundings.
