Is delta H negative indicative of an exothermic or endothermic reaction?
Understand the Problem
The question is asking whether a negative change in enthalpy (delta H) indicates an exothermic or endothermic reaction. Exothermic reactions release heat, while endothermic reactions absorb heat. Therefore, a negative delta H signifies that the reaction is exothermic.
Answer
exothermic
The final answer is exothermic
Answer for screen readers
The final answer is exothermic
More Information
In a chemical reaction, a negative ΔH indicates that the reaction releases heat to the surroundings, making it exothermic. Conversely, a positive ΔH means the system absorbs heat, indicating an endothermic reaction.
