The amount of activation energy related to whether a reaction is exothermic or endothermic?
The amount of activation energy required for a reaction is independent of whether the reaction is exothermic or endothermic. Activation energy is the energy needed to reach the transition state, allowing reactants to be converted into products. Exothermic reactions release energy as products form, while endothermic reactions absorb energy. Therefore, both types of reactions can have varying amounts of activation energy, depending on other factors such as the specific reactants and the reaction pathway.

Do exothermic and endothermic occur as bonds break and reform?
Yes, exothermic and endothermic reactions are related to the breaking and forming of bonds. In an exothermic reaction, energy is released when new bonds are formed, resulting in a net release of energy, while in an endothermic reaction, energy is absorbed to break bonds, leading to a net intake of energy. The overall energy change in a reaction depends on the balance between the energy required to break bonds and the energy released when new bonds are formed.
What is the name of the chemical reaction when energy is absorbed from the outside?
Endothermic reaction. See Related Link.
How is the deltaHt related to the delta of a reaction?
The change in enthalpy (ΔH) of a reaction, often referred to as delta H, represents the heat absorbed or released during the reaction at constant pressure. It is directly related to the change in internal energy (ΔU) of the system, as ΔH = ΔU + PΔV, where P is the pressure and ΔV is the change in volume. A negative ΔH indicates an exothermic reaction, while a positive ΔH indicates an endothermic reaction. Therefore, ΔH provides insight into the energy dynamics of the reaction and its favorability.
How how is the activation energy for a chemical reaction related to letter not a collision between molecules in the how is activation energy for a chemical reaction related to letter not a collision i?
The activation energy of a chemical reaction is the minimum energy required for reactant molecules to collide and form products. It represents the energy barrier that must be overcome for a reaction to proceed. If the energy of the colliding molecules is below this threshold, they will not react, regardless of their collision frequency. Thus, a higher activation energy means fewer effective collisions lead to products, slowing down the reaction rate.
What does it mean if the activation energy is high related to traveling?
If the activation energy elated to travelling is high, then a large amount of energy is required to start a chemical reaction. After the reaction is initiated, less energy is needed.
What types of energy are released in exothermic reactions?
Exo -> Greek "Outside" Therm -> thérmē -> Greek "Heat" So an exothermic reaction releases heat energy. Related to that type of reaction is the endothermic reaction in which heat is absorbed into the reaction rather than being released by it.
Do exothermic and endothermic occur as bonds break and reform?
Yes, exothermic and endothermic reactions are related to the breaking and forming of bonds. In an exothermic reaction, energy is released when new bonds are formed, resulting in a net release of energy, while in an endothermic reaction, energy is absorbed to break bonds, leading to a net intake of energy. The overall energy change in a reaction depends on the balance between the energy required to break bonds and the energy released when new bonds are formed.

How are energy inputs and outputs related to chemical reactions?
In chemical reactions, energy is either released (exothermic) or absorbed (endothermic). Energy input is required to break bonds in reactants, and energy output is released when new bonds form in products. The difference between energy input and output determines if a reaction is exothermic or endothermic.
Is silver nitrate and copper an exothermic reation?
yes, it's far from endothermic, because there is no internal change within the element related to structure or energy
What is the relationship between the rate constant of a reaction and the activation energy of the reaction?
The rate constant of a reaction is directly related to the activation energy of the reaction. A higher activation energy typically results in a lower rate constant, meaning the reaction proceeds more slowly. Conversely, a lower activation energy usually leads to a higher rate constant, indicating a faster reaction.
How temperature related to activation energy?
The relation is:k is the reaction rate coefficient.
How is the deltaHt related to the delta of a reaction?

How is activation energy related to bond energy?
Activation energy is the minimum energy required for a chemical reaction to occur. It is related to bond energy because breaking chemical bonds and forming new bonds requires energy, which contributes to the activation energy of a reaction. Bonds with higher bond energy are more stable and require more energy to break, hence increasing the activation energy of the reaction.
How the words catalyst enzyme and activation energy are related?
They are all used to start a reaction.
How is temperature related to a chemical reaction rate?
Ignition temperature is the temperature a substance needs to reach before it is combustible. Activation energy is the energy required to start a reaction occurring. Temperature is directly affected by heat. Heat is a form of energy. Therefore as you add energy to a substance it heats up. It will reach its ignition temperature and combust. The combustion is the reaction.
When ammonium chloride mixes with water the solution formed feels cold what type of reaction is this endothermic or exothermic?
When ammonium chloride dissolves in water, it is not a reaction at all, but only a dissolution. Since the solution formed feels cold, the dissolution is endothermic, absorbing heat from its surroundings.
