Which of the following statements is true about the activation energy of an endothermic reaction?(1 point)

Question

Responses

A small amount of energy is needed to activate the reaction.
A small amount of energy is needed to activate the reaction.

A high amount of energy is needed to activate the reaction.
A high amount of energy is needed to activate the reaction.

There is no need for activation energy in an endothermic reaction.
There is no need for activation energy in an endothermic reaction.

Activation energy will slow down an endothermic reaction.

Answer 1

The statement that is true about the activation energy of an endothermic reaction is:

A high amount of energy is needed to activate the reaction.

In endothermic reactions, energy is absorbed from the surroundings, and thus a sufficient amount of energy (activation energy) is generally required to initiate the reaction.
