In the following question a statement of Assertion (A) followed by a ...
Assertion (A): Electron gain enthalpy can be exothermic or endothermic.
Reason (B): Electron gain enthalpy provides a measure of the ease with which an atom adds an electron to form an anion.
Explanation:
- Electron Gain Enthalpy: Electron gain enthalpy is the energy change that occurs when an atom gains an electron to form an anion. It is the opposite of ionization energy, which is the energy required to remove an electron from an atom.
- Exothermic and Endothermic Reactions: Exothermic reactions release energy in the form of heat, while endothermic reactions absorb energy from their surroundings. In the context of electron gain enthalpy, exothermic reactions release energy when an atom gains an electron, while endothermic reactions absorb energy during this process.
- Assertion (A): The statement that electron gain enthalpy can be exothermic or endothermic is true. This is because the energy change that occurs when an atom gains an electron can either release energy (exothermic) or absorb energy (endothermic), depending on the specific atom and conditions.
- Reason (B): The statement that electron gain enthalpy provides a measure of the ease with which an atom adds an electron to form an anion is also true. Electron gain enthalpy is a measure of the energy change that occurs when an atom gains an electron, and it reflects the stability of the resulting anion. Higher values of electron gain enthalpy indicate that it is more difficult for an atom to add an electron and form an anion, while lower values indicate that it is easier for an atom to do so.
Conclusion: Both the assertion and the reason are true, and the reason is the correct explanation of the assertion. Electron gain enthalpy can be exothermic or endothermic, and it provides a measure of the ease with which an atom adds an electron to form an anion.
Reason (B): Electron gain enthalpy provides a measure of the ease with which an atom adds an electron to form an anion.
