Answer:
The correct option is c) exothermic, negative.
Explanation:
Reactions that releases heat to the surroundings are called exothermic, and are characterized by negative entalpy (ΔH) values.
A chemical reaction that releases heat to the surroundings is said to be exothermic and has a negative H at constant pressure.
This is the type of reaction which involves the release or loss of heat to the surrounding.
Since heat is lost, exothermic reaction has a negative enthalpy thereby making option C the most appropriate choice.
