Answer: False. The amount of entropy is increased when a chemical bond is broken between atoms. To elaborate we consider the following simple example of the ...

14 февр. 2022 г. · Bond enthalpies are always positive, because it's referring to the energy required to break a bond. Remember, breaking bonds require energy, ... Breaking Bonds and Making Bonds Forming/Breaking Bonds Bonds formed - negative? Week 5&6 Achieve #2 Другие результаты с сайта lavelle.chem.ucla.edu

17 окт. 2019 г. · A reaction is exothermic if more energy is released by formation of new bonds than is consumed by breaking old bonds. A reaction is exothermic ...

5 янв. 2024 г. · Since energy is needed to break the bond, the process is endothermic and thus bond energy is positive. If increasing entropy is preferred, then why is forming chemical ... Is entropy positive or negative for endothermic? - Quora If in exothermic reaction breakage of bonds occur ... - Quora Can you explain why entropy increases with temperature ...

27 июн. 2013 г. · If if takes less energy to break the original bonds than is released when new bonds are formed, then the net energy of the reaction is positive.

29 сент. 2024 г. · The change in energy is positive since the products have more energy than the reactants. The symbol ΔH is used to show the change in heat energy.

13 июн. 2014 г. · I do not think that an entropy decrease is a requirement to form a bond. Think about a "normal" case: HCl (a gas) and NHX3 (another gas) ...

11 июл. 2023 г. · Energy is released to generate bonds, which is why the enthalpy change for breaking bonds is positive. Energy is required to break bonds.

To determine how much energy will be released when we form a new bond rather than break it, we simply make the bond enthalpy value negative. Because bond ...
