Effects of temperature and pressure on exothermic and endothermic reaction?
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.
How can an endothermic reaction be spontaneous at room temperature?
An endothermic reaction can be spontaneous at room temperature if the increase in entropy of the system is large enough to overcome the energy input required for the reaction. This can happen if the products of the reaction have higher entropy than the reactants. As a result, the overall change in free energy can be negative even though the reaction is endothermic.
How do you predict if a reaction will be exothermic or endothermic?
Although it is hard to predict if a reaction will be exothermic or endothermic, there are many factors that can be considered when trying to determine it. first endothermic reactions usually employ the breaking of strong bonds, and the creation of weak bonds. While exothermic reactions usually break weak bonds and create strong bonds. Sadly these are the only ways to predict if a reaction will be endothermic or exothermic, altough there are other methods that could be used that are much more complex.
What does edothermic and exothermic mean?
Endothermic means that the reaction absorbs heat from the surroundings, and requiring energy be added to it in order for it to take place. An Exothermic reaction, however, releases heat into the surroundings as a result of the reaction.
What happens in a exothermic reaction?
In an exothermic reaction, heat is released to the surroundings. This typically results in an increase in temperature, and the surroundings feel warm. The reactants have higher energy than the products, and the reaction is often spontaneous.

What is endothermic and exothermic reaction?
Endothermic; that reaction in which energy is absorbed is called endothermic reaction, mostly the breaking of a molecule is an endothermic reaction, as for breaking process energy is required, when a molecule gets the sufficient energy it breaks. EXOTHERMIC Reaction is that in which energy is released, as combining of any two element or atoms to make a molecule, take the example of formation of CO2.
What does edothermic and exothermic mean?
Endothermic means that the reaction absorbs heat from the surroundings, and requiring energy be added to it in order for it to take place. An Exothermic reaction, however, releases heat into the surroundings as a result of the reaction.

In an exothermic reaction, heat is released to the surroundings. This typically results in an increase in temperature, and the surroundings feel warm. The reactants have higher energy than the products, and the reaction is often spontaneous.
Does endothermic have a 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.
In exothermic reactions the energy required to break the bonds in the reactants is greater than the energy released as the products form?
In exothermic reactions, the energy needed to break the bonds in the reactants is higher than the energy released when the products are formed. As a result, the excess energy is released to the surroundings in the form of heat. This results in a net release of energy during the reaction.
Given the reaction fe s - fes energy which is true It is exothermic The potentialenergyof the reactantis the same as the product The potentialenergyofthereactcantislowerthanthe product endothermic?
The reaction Fe(s) → FeS(s) is exothermic because it releases energy. The potential energy of the reactant is higher than that of the product in an exothermic reaction.
Are bats endothermic or exothermic?
Bats are endothermic, meaning they can internally regulate their body temperature. They are warm-blooded animals that maintain a constant body temperature, usually higher than their surrounding environment. This helps them to sustain their high metabolic rate required for flight and other activities.
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.
What reaction involves a net absorption of energy?
a reactions that has a net absorption is a endothermic reaction
