What is a example of how to supply activation energy to begin a reaction?
When a lit match is touched to the wick of a candle, the candle begins to burn. When the match is removed, the candle continues to burn.
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.

What percent of the US energy supply is coal?
Approximately 23% of the US energy supply comes from coal.
What is the formula for heat supplied to a chemical reaction?
The heat supplied to a chemical reaction can be calculated using the formula: q = m * c * ΔT, where q is the heat energy, m is the mass of the substance, c is the specific heat capacity, and ΔT is the change in temperature.
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 does an endothermic reaction require to continue?
An endothermic reaction requires a continuous input of energy to continue. This energy is needed to break bonds in the reactants and drive the reaction forward by absorbing heat from the surroundings. Without this constant energy supply, the reaction will slow down or stop.
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.
How do endothermic and exothermic reactions work together to supply energy?
Endothermic reactions absorb energy from their surroundings, while exothermic reactions release energy. In a system where both reactions are occurring simultaneously, the energy absorbed by the endothermic reaction can be used to drive the exothermic reaction forward, allowing for a continuous supply of energy within the system.
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.
