The activation energy diagram is drawn as a hill because there is a large amount of energy needed to form the unstable transition state (viewed as the upward slope on the diagram). The difference between this peak energy and the rectants' energy is the activation energy. When this state decomposes in to more stable products (which are more stable than the reactants), the energy of the molecules is lower, thus the downward slope after the peak.

-----------------------------

Activation energy is the energy at the potential barrier between the two fields with low energy (at left and at right) representing the sum of energies of reactants and products; the reaction is possible if the activation energy can exceed this barrier. And in a graphic this is the pic of a hill.

How does an enzyme catalyze a chemical reaction in regards to activation energy?

Any catalyst will make a chemical reaction easier or quicker to happen by lowering the activation energy. On a energy diagram, you will see a lower "hill" for activation energy, which corresponds to less energy required to begin the reaction.


What does the energy hill represent of an energy diagram?

The energy hill on an energy diagram represents the activation energy required for a chemical reaction to occur. It shows the energy difference between the reactants and the transition state of the reaction. The height of the energy hill determines the rate at which the reaction will proceed.


What does the energy hill represent on a energy diagram?

The energy hill on an energy diagram represents the activation energy needed for a chemical reaction to occur. It shows the energy barrier that must be overcome for the reaction to proceed from reactants to products. The height of the hill indicates the energy input required for the reaction to take place.


Which has the highest activation energy?

If the activation energy of a reaction is high, then it requires a large amount of energy to initiate the reaction. The situation arising when a spontaneous reaction has a large activation energy is similar to rolling a ball over a hill. At first, energy must be expended to move the ball to the crest of the hill (or, in the case of a reaction, impart enough energy to the molecules so that their bonds can be sufficiently weakened). However, once the ball is at the top of the hill, it rolls down on its own. This is analogous to the reforming of chemical bonds, which releases energy. High activation energies are typical when a reaction involves molecules whose bonds are strong.


What does energy hill diagram represents?

An energy hill diagram represents the energy changes that occur during a chemical reaction. It visually shows the difference in energy between reactants and products, with the peak representing the activation energy needed for the reaction to occur.


Reactants and products in an energy diagram?

Activation energy is the distance from the reactants to the top of the "hill."


Which analogy can best be likened to the activation energy of a chemical reaction?

The activation energy of a chemical reaction can be likened to pushing a car up a hill before it can roll down to the other side. Just like how the initial push is needed to start the motion, the activation energy is required to initiate a chemical reaction. Once the reaction is started, it can proceed spontaneously.

What occur in a chemical reaction and why are chemical reaction important?

This is the energy needed to get us from our starting point to the top of the hill would be the activation enery


When you Reduce activation energy what happens?

Reducing activation energy allows chemical reactions in the cells of living things to occur at temperatures at which the cells can survive. Reducing activation energy is carried out by enzyme catalysts. The enzyme catalysts are not used up in the reaction, and can be used in subsequent chemical reactions.
