When a chemical reaction has a negative delta G, the reaction is exothermic because delta G is the change in energy of a system and the change in its entropy. If the effect of a reaction is to reduce G, the process will be spontaneous so delta G is negative.

Hope this helps :)

Is silicon endothermic or exothermic?

Silicon is neither endothermic nor exothermic on its own. Endothermic and exothermic refer to the absorption or release of heat during a chemical reaction, which silicon does not undergo in its elemental form.


What is the diffrencence between exothermic reaction and chemical reaction?

A chemical reaction is a process that involves the breaking and forming of chemical bonds to create new substances. An exothermic reaction is a type of chemical reaction that releases heat energy to the surroundings. In other words, all exothermic reactions are chemical reactions, but not all chemical reactions are exothermic.


What is a chemical reaction that absorbs heat?

An example of a chemical reaction that absorbs heat is the reaction between baking soda (sodium bicarbonate) and vinegar (acetic acid) to produce carbon dioxide gas. This reaction is endothermic, meaning it absorbs heat from its surroundings, causing the mixture to feel cold to the touch.


Are single replacement reactions endothermic or exothermic?

Single replacement reactions can be either endothermic or exothermic, depending on the specific reaction. The energy change of the reaction will determine whether it is endothermic (absorbs heat) or exothermic (releases heat).


Is magnesium ribbon burns an endothermic reaction or an exothermic reaction?

The reaction is highly exothermic as heat energy is released from the system to the surroundings whereas in endothermic the heat is absorbed from the surroundings into the system and you can also observe or see the smoke coming out of the apparatus in which the reaction is occurring or taking place.Heat energy is being released in the form of smoke.Therefore the reaction is exothermic.

Is the reaction endothermic or exothermic, and what is the enthalpy of the reaction?

The reaction is exothermic, meaning it releases heat. The enthalpy of the reaction is negative, indicating that it is exothermic.


What is the opposite of exothermic?

The opposite of exothermic is endothermic. Exothermic reactions are those which give off energy in the form of heat. Endothermic reactions require energy.


Are titrations endothermic or exothermic?

The reaction is exothermic.


Is the reaction of magnesium sulfate and water exothermic or endothermic?

It is not a chemical reaction, it is dissolution; this physical process is exothermic.


Which contains more chemical energy endothermic or exothermic?

An endothermic reaction contains more chemical energy.


What endothermic reaction?

An endothermic reaction is a chemical reaction in which energy (heat, light, etc.) is absorbed instead of released as in a exothermic reaction.


What type of chemical absorbs energy?

The two kinds of chemical reactions are endothermic and exothermic. A chemical reaction that absorbs energy is called an endothermic reaction.


Is reactants to products endothermic?

Not always. In a chemical reaction, the process can be either endothermic or exothermic. Endothermic reactions absorb heat from the surroundings, while exothermic reactions release heat into the surroundings. The specific reaction will determine whether it is endothermic or exothermic.


What is the difference between a exothermic chemical reaction and a endothermic chemical reaction?

energy released by the reaction or energy absorbed.


What is the name given to reactions which take in heat?

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.
