To determine when the electron affinity (EA) is positive, let's analyze the concept step by step:Step 1: Understanding Electron Affinity Electron affinity is the amount of energy released or absorbed when an electron is added t

Enthalpy: The enthalpy of reaction indicates whether the reaction is endothermic (absorbs heat) or exothermic (releases heat) by the sign of the value. Endothermic reactions have a positive enthalpy, while exothermic reactions have a negative enthalpy. ...

CO bonds have a greater bond-cleavage enthalpy of (799 kJ mol−1), allowing for the development of MOFs that bypass the weaker C–C (347 kJ mol−1) in the main chain or open the benzene branch (518 kJ mol−1) of plastic polymers.33 Second, several novel MOFs have been ...

Yes there is bond formation, henceexothermic, negative enthalpy change in rate of reactive (-ve delta H), energy is released. Acid metal reactions usually produce a salt, in this case, zinc chloride and hydrogen gas. ... That's due to heat energy which is being released from the reaction...
