Does the following reaction absorb or release energy? release absorb Can't be decided with the data given. Is it possible to calculate the amount of energy absorbed or released by reaction (1) using only the data above If you answered yes to the previous question, enter the amount of energy absorbed or released by reaction (1): l k//mol Does the following reaction absorb or release energy? absorb (2) Te+(z) + e- Te(R) Can't be decided with the data given. Is it possible to calculate the amount of energy absorbed or released by reaction (2) using only the data above? If you answered yes to the previous question, enter the amount of energy absorbed or released by reaction (2) kJ/mol Explanation 0 2 4Explanation / Answer
1. Removal of electron from an anion is reverse of adding an electron to a neutral atom which is energy releasing process. Thus,removal of electron from anion is energy absorbing process.
Yes. It is possible to calculate the energy absorbed
The energy absorbed is equal to electron affinity of the neutral atom = 190.2 kJ/mol
2. Addition of electron to a cation is reverse of ionization of a neutral atom. Ionization is an energy absorbing process thus addition of electron to a cation is energy releasing process.
Yes.The quantity of energy released can be measured and is equal to ionization energy.
Energy released = 869.3 kJ/mol
