No, the spontaneity of reactions is not always associated with exothermic heat release. Some spontaneous reactions can be endothermic, meaning they absorb heat from their surroundings.

Is the spontaneity of exergonic reactions determined by their tendency to release energy?

Yes, the spontaneity of exergonic reactions is determined by their tendency to release energy.


Reactions that release heat as bonds are broken are called .?

exothermic


What kind of reactions release energy?

Exothermic reactions release energy.


How are exothermic and exothermic reaction are different and how are they the same?

Endothermic and exothermic reactions are similar in that both have reactants and products. They are different in that exothermic reactions release energy through reacting and endothermic reactions absorb it.


What type of reactions always release energy?

exothermic reactions


Are exothermic reactions faster than endothermic reactions?

In general, exothermic reactions are faster than endothermic reactions. This is because exothermic reactions release energy, which can help drive the reaction forward more quickly.


Reactions that release energy are termed?

Exothermic


What do exothermic reactions achieve in terms of energy release and temperature change?

Exothermic reactions release energy in the form of heat, causing an increase in temperature.


Contrast endothermic and exothermic reactions?

Endothermic reactions are chemical reactions that use heat as part of the reactant. Heat is absorbed into the reaction in order for it to continue. Exothermic reactions are chemical reactions that release heat as a product of the reaction.


What name is given to all chemical reactions which releases heat energy?

Exothermic reactions produce heat. Endothermic reactions take in heat from the surrounding area and get cold.


How is endothermic reactions differ from exothermic reactions?

Endothermic reactions absorb heat from the surroundings, causing a decrease in temperature. In contrast, exothermic reactions release heat into the surroundings, leading to an increase in temperature. Endothermic reactions have a positive enthalpy change, while exothermic reactions have a negative enthalpy change.


Chemical reactions that release energy do if occur or don't?

These are called exothermic reactions.
