If the temperature rises, the reaction is EXOTHERMIC where the system (reaction) is giving off heat to the surroundings (water, beaker, test tube, etc.).

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 does temperature affects the rate of industrial reaction?

It depends. A higher temperature will speed up an endothermic reaction, but slow down an exothermic reaction.


How do you know if an enthalpy change diagram is endothermic or exothermic?

If you plot the reaction coordinate (what I think you mean by "enthalpy change diagram"), the reaction will be exothermic if the products are lower on the graph than the reactants. If they are higher than it is endothermic. For instance, if you go to the linked Wikipedia page (link to the left of this answer), the graph shown is of an exothermic reaction.


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 to the reaction 2 N O 2 in equilibrium with N 2 O 4 plus 57.3 kilojoules when the temperature of the reaction is increased?

This is an endothermic equilibrium reaction Thus, increase temperature will push the reaction to the right. So more N2O4 is produced

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 is an endothermic reaction?

An endothermic reaction is one that absorbs heat from the surroundings.

What is an another name for exothermic and for endothermic reactions?

it is a Many chemical reactions release energy in the form of heat, light, or sound. These are exothermic reactions. Exothermic reactions may occur spontaneously and result in higher randomness or entropy (ΔS > 0) of the system. They are denoted by a negative heat flow (heat is lost to the surroundings) and decrease in enthalpy (ΔH < 0). In the lab, exothermic reactions produce heat or may even be explosive. There are other chemical reactions that must absorb energy in order to proceed. These are endothermic reactions. Endothermic reactions cannot occur spontaneously. Work must be done in order to get these reactions to occur. When endothermic reactions absorb energy, a temperature drop is measured during the reaction. Endothermic reactions are characterized by positive heat flow (into the reaction) and an increase in enthalpy (+ΔH).


Which reaction is the product higher in energy than the reaction?

Endothermic


Does an exothermic reaction contain more chemical energy than reactants?

depends , if the reaction is endothermic or exothermic. if the reaction is endothermic , the energy needed to break the bonds is greater than the energy that forms bonds.and to break bonds you need thermal energy , meanwhile forming bonds gives off energy. now if the reaction is exothermic the energy given off the bonds form are greater than the enrgy needed to break them. you know if the reaction is exothermic or endothermic because exothermic have a negitave delta next to d eqn.while endothermic have a positive delta.


The heat energy content of the reactants of an endothermic reaction compared with products is?

In an exothermic reaction the reactants release energy to the environment when they react - like coal burning. In an endothermic reaction the reactants need to absorb energy from their environment when they react, so the reaction feels cold in your hand, or else you have to heat it continually to make it react. The products would then be at a higher energy level than the reactant were. Photosynthesis is an interesting example of an endothermic reaction, because in this example the energy supplied to make the reaction go is not heat but light. The product (sugar) is an 'energy store' which the plant (or whatever eats the plant) can use later on to release the energy in respiration.


What is the sign of the enthalpy change for an endothermic reaction?

Endothermic reaction: In an endothermic reaction, the products are higher in energy than the reactants. Therefore, the change in enthalpy is positive, and heat is absorbed from the surroundings by the reaction therefore enthalpy change show positive sign in a endothermic reaction..


What happens to the reaction 2 N O 2 in equilibrium with N 2 O 4 plus 57.3 kilojoules when the temperature of the reaction is increased?

This is an endothermic equilibrium reaction Thus, increase temperature will push the reaction to the right. So more N2O4 is produced
