Activation energy is the minimum amount of energy needed for the reactants to get converted to products. It can be supplied as heat energy, electrical energy, mechanical energy, and light energy.

What is the term for the energy responsible for the variations in the reaction rates of chemical processes?
It's hard to know precisely what is meant by this question. You may be thinking of activation energy, the minimum energy needed to start the reaction, which explains why one reaction may go at a different speed from another. On the other hand, if you are thinking of just one reaction going faster and slower depending on the energy supply, then that's most often thermal energy.
How might you cause an edothermic chemical change to begin and keep going?
By supplying energy to it.Explanation:Since an endothermic reaction, by definition, NEEDS energy to go on, it will cool down (= taking heat energy from the reactants). It will stop itself as any reaction will slow down at lower(ing) temperatures.So SUPPLY of heat is at least necessary to KEEP temperature at its minimum level of 'ongoing' reaction.

Why do glow sticks run out?
Glow sticks create energy when two separate chemicals are mixed. A fluorescent dye absorbs the energy from the reaction and creates light. Eventually the two chemicals are completely reacted and can no longer supply energy to the dye. The chemicals normally used are phenyl oxalate and hydrogen peroxide. When the inside container is ruptured, they mix. The oxidation reaction creates a peroxyacid ester which rapidly decomposes into carbon dioxide and releases photons into the fluorescent dye in the mix. The reaction also releases phenol, which can be harmful.
What is the formula for heat supplied to a chemical reaction?
calculate heat of reaction u ll get the idea ....how much heat need to supply for reaction
Is eating an example of activation energy?
no
In a chemical reaction what does it take energy to do?
For most chemical reactions, energy is required to supply an "activation energy" required before reaction.
How do you supply activation energy begin a reaction?
Generally, the activation energy is given by heat, so, you must watch carefully the temperature of the reaction, because you can get undesired products in the reaction, or yielding nothing at all.

Which molecules lower the activation energy?
Enzymes lower the activation energy of reactions.The activation energy of a reaction is the amount of energy that has to be put into the system before the reaction proceeds of its own accord. It is like setting fire to a log. First you must supply enough energy by burning a match, paper, kindling, and so on, until the log is hot enough to catch and continue burning on its own. This energy that you supply is the activation energy.When an enzyme is present, the activation energy is lower, and so the reaction proceeds more readily at the temperature of the organism. A concept known as the induced-fit modelexplains how enzymes lower activation energy, by suggesting that the interaction of a substrate with an active site on the surface of the enzyme causes a change in the enzyme's shape, which in turn affects the substrate in such a way as to encourage the reaction.
Do enzymes work by providing energy to initiate reaction?
No they do not supply energy to start a chemical reaction, however energy has something to do with it. Enzymes actually lower energy barriers, in other words it reduces the activation energy needed which is the energy absorbed before the chemical reaction can start.

What kind of chemical reaction needs a constant supply of energy?
If a reaction requires a constant input of energy, the products are higher in energy than the reactants. This type of reaction is known as endothermic, since it involves an increase in energy of the system. Conversely, reactions that release energy are known as exothermic.
What is the concept of the dark reaction as it relates to photosynthesis?
The dark reaction as it pertains to photosynthesis occurs when the plant, in the absence of sunlight, continue to supply energy. The dark side of photosynthesis relies upon the stored starches to fuel the energy cycles.
How much heat does a reaction produce?
The amount of heat produced in a reaction is not fixed. It depends upon the total amount of energy change that has taken place in the reaction altogether. Not only this, all reactions do not produce heat. In some cases we have to supply energy from external sources to get the reaction started.
How are chemical reactions different to reversable changes?
physical change is reversible because you can undo it for example: if you fold a paper you unfold the paper. chemical chang is irreversible because if you make somthing together you could not seperate them.
What would be the advantages in using nuclear fusion to supply your energy needs in the future?
Tho only waste products would be Helium and a very small volume of the reactor that had become radioactive from neutron activation.
