What else can I help you with?
A change of state reaction that absorbs energy is endothermic?
yes it is endothermic
Which change of phase is endothermic?
is Absorbs If you are asking if a change of state is why a reaction may be endothermic, is not always true. It simply depends on what the change of state is to and what it is from, ex: a change from liquid to solid is usually exothermic because it losses energy as the particles slow down and draw near to eachother... and the opposite occurs from solid to liquid (or liquid to gas).
A change in matter in which energy is taken in is an endothermic change?
Endothermic changes are processes where energy is absorbed by the system from its surroundings. This results in a decrease in temperature in the surroundings during the process. Examples include melting ice and evaporating water.
The change in which ice absorbs energy and melts is?
An endothermic change; or a change of state. Endothermic because it absorbs energy. Change of state because ti changes from a solid to a liquid.
A change of state where energy is given off?
This process is called exothermic reaction, where energy is released in the form of heat. It typically involves a change from a higher energy state to a lower energy state, resulting in the release of energy to the surroundings. An example would be the solidification of molten lava into solid rock, releasing heat energy in the process.
Why is the activation energy of an endothermic reaction is at least as large as its enthalpy?
The activation energy of an endothermic reaction is at least as large as its enthalpy change because the reactants require a minimum amount of energy to reach the transition state where bond-breaking and bond-forming occur. The enthalpy change represents the overall energy difference between reactants and products but does not account for the energy needed to overcome the energy barrier (activation energy) for the reaction to proceed.
Is sublimation exothermic or endothermic?
Sublimation is an endothermic phase transition from solid to gaseous state.
What has a change of state reaction that energy is endothermic?
One example of a change of state reaction that absorbs energy is the melting of ice. When ice melts and changes from a solid to a liquid state, it absorbs heat from its surroundings to break the intermolecular forces holding the water molecules together in a rigid structure. This absorption of energy is why melting ice feels cool to the touch.
What will the profile for endothermic and exothermic with the catalyst added?
In the presence of a catalyst, both endothermic and exothermic reactions will have their activation energy lowered, allowing them to proceed more quickly. For endothermic reactions, the overall energy profile shows a reactant state with lower energy than the products, but the catalyst reduces the energy barrier for the transition state. In exothermic reactions, the reactants start at a higher energy level than the products, and again, the catalyst facilitates the reaction without altering the energy difference between reactants and products. Thus, while the catalyst speeds up the reaction, it does not affect the overall energy change (ΔH) for either type of reaction.
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.
can you relate endothermic and exothermic reactions to specifically the making and breaking of bonds?
An exothermic reaction releases energy when bonds are formed, leading to a lower energy state compared to the reactants. In contrast, an endothermic reaction requires energy input to break existing bonds and form new ones, resulting in a higher energy state than the initial reactants.
Is the melting of candle wax and exothermic or endothermic change?
The answer is endothermic. The wax is absorbing heat energy, not producing it, and changing from a solid state to a liquid state. If the reactants require more energy than than they are putting out during the reaction, it is said to be endothermic (absorbing of heat). If the reactants give off heat of their own (self sustaining), then it is an exothermic reaction. There are components in some types of wax that will burn, in which case that is an example of an exothermic reaction, but most wax will stop once the heat source is removed.
