An endothermic reaction would not necessarily have either a high or low activation energy; it could be either and would depend on the reactants. Also, the activation energy alone does not determine if a reaction is endothermic or exothermic; a low or high activation energy could be part of an endothermic or exothermic reaction, again depending on the reactants.

Does gamma have high or low energy?
Gamma have very high energy.
Does a high-efficiency machine degrade a relatively high or low percentage of energy to thermal energy?
It degrades a low percentage.
Do photon have a greater energy than electron?
No. A photon has no rest mass an electron has mass.
What energy do waves with a short wavelength have?
It's possible it has low energy and high frequency.
What is difference between low grade energy high grade energy?
Low-grade energy: Based on the thermodynamic concepts, an energy source can be called as high-grade or low-grade, depending the ease with which it can be converted into other forms. Thus electrical energy is called a high-grade energy, as it is very easy to convert almost all of it into other energy forms such as thermal energy (say by using an electrical heater). Whereas, it is not possible to convert thermal energy completely into electrical energy (typical efficiencies of thermal power plants are around 30 percent), hence thermal energy is called a low-grade energy. Naturally, high-grade energy sources are more expensive compared to low-grade energy sources.
Does endothermic have high or low activation energy?
An endothermic reaction would not necessarily have either a high or low activation energy; it could be either and would depend on the reactants. Also, the activation energy alone does not determine if a reaction is endothermic or exothermic; a low or high activation energy could be part of an endothermic or exothermic reaction, again depending on the reactants.
You may normally expect a slow reaction if a low activation energy is required?
Explain why a high energy of activation causes a reaction to be slow?
Are endothermic reaction products stable?
It depends on a few things. If you mean thermodynamically stable, then no. The product of an endothermic reaction is higher in potential energy than the reactant(s) and will eventually release that energy and revert back (if it doesn't go on to some other product). If you mean kinetically stable, then maybe. It really depends on the relative energy of any intermediates formed in the conversion of reactant(s) to product(s). This relative energy is also known as activation energy. If the activation energy is high, then the product would be relatively stable. If the activation energy is low, then the product would not be stable.
Energy of activation is?
The energy need to activate something depends on what is being activated. These energies can range from high to low.
The activation energy for the chemical reaction in living thing is high or low?
It is high because the enzymes in cells speed up the reactions by lowering the energy.
Is the activation energy for chemical reactions in living things high or low?
Activation energy of reaction is the same regardless if it is in living organism or in test tube. Yet, the energy of activation can be lowered if catalyst is present. In living things catalyst lower the energy needed for chemical reactions.
Energy required to start chemical reaction?
Energy required for a reaction can vary. Depending on the atom it changes. The element will be more reactive if it has a low 1st ionization energy since it requires less energy to react. The most reactive element in Francium since it has the lowest 1st ionization energy level. If an element has a high electro-negativity then it will also be able to react with little 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!
How do you use the word endothermic in a sentence?
Most endothermic reactions will stop once the temperature becomes too low. Stars cannot make energy from fusing iron into nickel since it is an endothermic process.
What is the difference between high quality and low quality energy?
The main difference between high quality and low quality energy is in the perception. This will facilitate the proper grading of tasks with the high tasks using high energy and low tasks low energy.
Does Rb have a high ionization energy or low ionization energy?

Does Kr have high ionization energy or low ionization energy?
