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
In a protein complex for the light reaction why is energy transferred from pigment molecule to pigment molecule to a special chlorophyll a molecule and eventually to the primary electron acceptor?
The molecular environment lets it boost an electron to a higher energy level and also to transfer the electron to another molecule
What is the ionizaton energy present example?
The energy required to remove electron from atom are called ionization energy. Larger atom or molecule have lower ionization energy and molecule have higher ionization energy.
How does activation energy determine if a reaction will release or absorb energy?
Activation energy is really just the minimum amount of energy needed for a chemical reaction to occur. Without it, the energy will stay the same and the substance cannot undergo a chemical change. The thing to look at, I think, is the product of the reaction. For example, in a graph, two substances could have the same activation energy, but after the reaction the amount of energy in substance 1 could be extremely low and the amount of energy in substance 2 could be higher than the activation energy. In substance 1, evidence of an EXOTHERMIC reaction has occurred because the amount of energy in the original substance was lost indicating that it has released energy. Whereas in substance 2, when the amount of energy was higher than the activation energy, it is evident that an ENDOTHERMIC reaction has occurred because the amount of energy after the reaction is higher than it was before the reaction. This shows that substance 2 absorbedenergy making it endothermic. hope this helps!

Why is the activation energy of an endothermic reaction is at least as large as its enthalpy?
In an endothermic reaction the energy of the products is higher than the energy of the reactants. The activation energy also is an energy increase. The activation energy must be at least as high as the products energy or the reaction would never take place. Thus, the activation energy must be at least as large as the enthalpy in an endothermic reaction.

What are slowed reactions?
Chemical reactions that have high activation energy, with multiple intermediates and transitions states that have higher activation energy than the initial requirement, but which still have a negative Gibbs free energy change.
Is IT true the higher the activation energy of a chemical reaction the easier it will be to get the reaction started.?

How does gas explode?
Gasses in the atmosphere are given some energy (activation energy), this energy is used for the activation of the explosion. As a few gas particles react, they then have higher energy and as they collide into other air particles it causes them to react. This happens rapidly and thus an explosion occurs. I think. Think of it as an exothermic reaction, but uncontroled.
A catalyzed reaction will have a activation energy and this leads to a in the reaction rate. A) lower decrease B) lower increase C) higher decrease D) higher increase?

Do catalyzed or uncatalyzed reactions require more activiation energy?
Catalyzed reaction has a lower activation energy because there is an enzyme present in the reaction. Uncatalyzed reaction has a higher activation energy because there is no enzyme present in the reaction.
When the molecules in a gas heat up?
When a gaseous molecule got heated up, it gain energy and then momentum that makes the molecule rises up higher.
What is the transfer of heat energy?
thermal energy. The transfer of heat happens when a warm fast moving molecule run into slow a cold ones the heat is then transferred from the warm molecule to the cold oneAnswerHeat is energy in transit from a higher temperature to a lower temperature. Heat isn't transferred; heat describes the process of transfer.
