Q: Which of the following is true about an exothermic reaction?
Solution:
In an exothermic reaction, the enthalpy change (ΔH) is negative because heat is released.
Steps: 5
Show Steps
Step 1: Understand what an exothermic reaction is. It is a type of chemical reaction that releases heat.
Step 2: Learn about enthalpy change, which is a measure of heat content in a system.
Step 3: In an exothermic reaction, the system loses heat to the surroundings.
Step 4: Because heat is released, the enthalpy change (ΔH) is negative.
Step 5: Remember that a negative ΔH indicates that energy is being released during the reaction.
