What term refers to a chemical reaction that absorbs heat energy?
Absorbing energy from the surroundings is endothermic. (The opposite - releasing energy to the surroundings - is exothermic).
What does enegery need to get a reaction?
In order to initiate a chemical reaction, energy is needed to break the existing bonds in the reactants. This initial input of energy is known as the activation energy. Once the bonds are broken, new bonds can form and the reaction proceeds to completion, releasing or absorbing energy in the process.
How do you determine whether a reaction is spontaneous or non spontaneous?
The first of two factors that determine whether a reaction is spontaneous or non-spontaneous is entropy. The second is energy. For a reaction to be spontaneous, it must have both of these factors.
How does Gibbs free energy predict spontaneous?
If G < 0, the reaction is spontaneous.
What is a reaction which takes in energy?
endothermic
Why do energy absorbing reactions react spontaneous?
it doesn't its energy releasing reaction
What is the opposite of a reaction releasing energy?
A reaction releasing energy is called an exergonic reaction, so the opposite of the would be a reaction that needs energy to take place, called an endergonic reaction. These are also known as exothermic and endothermic reactions.
What is the difference between energy releasing reaction and energy absorbing action?
Beacuse when you release energy out of your body or somthing, somthing has to take in the energy so absorbing;SO, it's like a chain reaction you release somthing els takes in, like humans breath oxygen plants breath our carbon dioxide and plants give us oxygenSo, it differs because when energy-realses somthing needs to take that energy in as in absorbing
What type of chemical reaction occurs spontaneously?
Spontaneous chemical reactions are those that release energy and result in a decrease in free energy. They typically involve exothermic reactions where the products are more stable than the reactants, leading to a natural tendency for the reaction to occur without the input of additional energy. Examples include combustion reactions and some types of oxidation-reduction reactions.

Absorbing energy from the surroundings is endothermic. (The opposite - releasing energy to the surroundings - is exothermic).
What is true about the numerical value of the Gibbs free-energy change for a spontaneous reaction?
For a spontaneous reaction, the numerical value of the Gibbs free-energy change (ΔG) is negative, indicating that the reaction is energetically favorable and will proceed in the forward direction. This negative ΔG means that the system is releasing energy and increasing in entropy during the reaction.
What kind of enthalpy change favors a spontaneous reaction?
For a spontaneous reaction, the overall change in enthalpy should be negative (exothermic). This means that the products have a lower enthalpy than the reactants, releasing energy in the form of heat.
A reaction in which it seems no activation energy is needed?
a spontaneous reaction

What is the difference between a reaction that happens spontaneously and a reaction that doesn't?
The difference can be clarified by entropy (the second rule of thermodynamics).The reaction is more spontaneous with higher entropy, for the reactions that occur spontaneously the entropy is higher than for the ones that do not.
