For any electron donor system, the energy released will be higher when the electron accepting system is more electron deficient. This means if the electron accepting system has higher oxidation number of high electropositivity, the the energy released will be higher.
For H2 as an electron donor system also, this principle will be true. Hence the energy released will be higher in case of a better electron accepting system.
What different amounts of energy are released when H, reacts as an electron donor with different...
Why is energy/heat released when a metal reacts with water?
The electron affinity is the energy released when an electron is added to a neutral atom to make a 1- anion. The table below shows the electron affinities for the 2nd period (row) elements. The value reported is the amount of energy released when an electron is added to a neutral atom. If no energy is released the anion is not stable and that is reported. Explain the overall trend of electron affinity increasing as you move left to right...

When 13(g) reacts with CIZ(g) to form ICKg) according to the following equation, energy is released into the surroundings. 12(g) + Cl2(g) 21CI(g) Is this reaction endothermic or exothermic? What is the sign of AH for the reaction? Would the energy of the surroundings increase or decrease as a result of this process? LLLLL
