endothermic, increasing entropy
No, a catalyst does not change the overall energy of a reaction. It only lowers the activation energy required for the reaction to occur. Therefore, a catalyst cannot change an endothermic reaction into an exothermic one.
The energy needed to support the endothermic reaction is supplied by the solution; thus the solution temperaturedecreases.If the reaction were exothermic, the solution temperature would increase.
An increase in temperature favours an endothermic reaction over an exothermic one as an endothermic reaction takes in the energy from the higher temperature more easily than the exothermic reaction gives out even more energy to the surroundings. Therefore an increase in temperature increases the level of completion and viability of an endothermic reaction, and the opposite for an exothermic reaction. An increase in pressure favours any reaction that forms fewer molecules from more molecules. It does not necessarily favour an exothermic or an endothermic reaction as it depends on the number of molecules on either side of the reaction. An endothermic reaction involves the breaking of bonds to a greater extent than an exothermic reaction, so an increase in pressure would, in a lot of cases, favour the exothermic reaction more than the endothermic reaction.
Endothermic reactions are characterized by the release of heat during the reaction. A typical example is the combustion of methane, which when combined with oxygen releases water and carbon dioxide.
endothermic, increasing entropy
An endothermal (or endothermic) process is the name of the process in which heat is taken in. In an exothermal (or exothermic) process, heat is released.
An endothermic reaction is one in which thermal energy, or heat, is absorbed. If heat is absorbed in the reaction process, it is endothermic. By monitoring the temperature of the reactants in a reaction, an observer could identify an endothermic reaction through observation of a decrease in the temperature.
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.
An endothermic reaction absorbs heat from its surroundings to proceed, resulting in a decrease in temperature of the surroundings. This decrease in temperature would be observed on a thermometer, as the heat is being taken in by the reaction rather than being released into the environment.
You would have to have an Eacthomatdid reaction of chemcal chance to change a cold pack to a hot pack.
No, a catalyst does not change the overall energy of a reaction. It only lowers the activation energy required for the reaction to occur. Therefore, a catalyst cannot change an endothermic reaction into an exothermic one.
does it matter? an exothermic reaction has heat as a biproduct of the product while an endothermic reaction has heat as a part of the reactants. meaning heat is released in exothermic and absorbed in endothermic
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.
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.
The energy needed to support the endothermic reaction is supplied by the solution; thus the solution temperaturedecreases.If the reaction were exothermic, the solution temperature would increase.
The temperature will decrease.
