Is kinetic energy a source of activation energy?
No, kinetic energy is not a source of activation energy. Activation energy is the minimum amount of energy required to start a chemical reaction, while kinetic energy is the energy of motion possessed by an object.
What is the source of activation energy during chemical reaction?
A catalyst.
Which pathway has the greatest activation energy?
The pathway with the greatest activation energy is often one that involves breaking strong chemical bonds or complex rearrangements, such as in nuclear reactions or some enzyme-catalyzed processes. These reactions require more energy input to initiate the reaction compared to other pathways with lower activation energies.
If one molecule has more energy than another does it have a higher activation energy?
The activation energy refers to a chemical reaction.
What is it called when energy is required to start a chemical reaction?
An exergonic reaction is activation energy (or energy of activation). An endergonic reaction is essentially the opposite of an exergonic reaction.
Why do living things use enzymes instead of a heat source of activation energy?
Living things use enzymes instead of a heat source of activation energy because they speed up chemical reactions as well as the metabolism in those living things.
What is the minimum amount of energy needed to start a chemical reaction?
The minimum amount of energy needed to start a chemical reaction is called the activation energy. It is the energy required to break the bonds in reactant molecules and initiate the reaction. Once this energy barrier is overcome, the reaction proceeds without additional energy input.
Which is the best description of activation energy?
The amount of energy needed to start a chemical reaction. Source: Biology class

The smallest amount of energy needed to start a chemical reaction is called?
Technically, it isn't "heat" that makes a chemical reaction happen. "Heat" is merely the flow of energy from one place to another. It is the energy itself that causes a reaction to occur. As an increase in temperature occurs, there is an increase in the energy in a group of molecules by making them mover around faster and bum into each other more. This energy is called "Activation energy", and is defined as the amount of energy required to make the reaction start and carry on spontaneously. Higher activation energy implies that the reactants need more energy to start than a reaction with a lower activation energy. With that being said, activation energy is the answer
What corresponds to the faster rate a mechanism with a small activation energy or one with a large activation energy?
A mechanism with a small activation energy corresponds to a faster rate of reaction. This is because lower activation energy means that more molecules have enough energy to overcome the energy barrier and react at a given temperature. In contrast, a mechanism with a large activation energy typically results in a slower reaction rate, as fewer molecules can achieve the necessary energy to initiate the reaction. Thus, lower activation energy leads to a higher reaction rate.
