Question

In which reaction would the activation energy result in an endothermic reaction?

Answer 1

The activation energy is the minimum amount of energy needed for a reaction to occur. For the reaction to be an exothermic reaction, the energy of the products should be less than the energy of the reactants where the excess energy is given off by the reaction in the form of heat or light.

Answer 2

Answer: B. An egg cooking.

Explanation: Endothermic reactions ABSORBS heat from its surroundings. The new substance will need more energy to form its chemical bonds than the old substance releases. Since the egg is cooking, that obviously means you are using heat to cook the egg. So, the egg absorbs the heat in order to cook properly.
