Which of the following statements is true for an exothermic reaction?

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 in a reaction, it means the system is losing energy.
Step 3: Learn about ΔH, which stands for the change in enthalpy (or heat content) of the reaction.
Step 4: In an exothermic reaction, since heat is released, the value of ΔH becomes negative.
Step 5: Conclude that the true statement for an exothermic reaction is that ΔH is negative.
