Answer:
c. endothermic reaction
Step-by-step explanation:
The given information states that the amount of energy required to break the bonds of the covalent compound is 1254 kJ, and the energy produced as a result of breaking the bonds is 1001 kJ.
In an endothermic reaction, the energy required to break the bonds is greater than the energy released or produced. This means that more energy is absorbed from the surroundings than is released during the reaction. In this case, since the energy required to break the bonds (1254 kJ) is greater than the energy produced (1001 kJ), it indicates that the reaction requires an input of energy from the surroundings, making it an endothermic reaction.
Option c, "endothermic reaction," is the correct answer based on the given information.
