the reaction associated with the ionization energy of lithium

Explanation:

An endothermic process is any process which requires or absorbs energy from its surroundings, usually in the form of heat.

the reaction associated with the ionization energy of lithium:

Ionization energy is endothermic because it requires an energy input to occur, we need to supply energy to remove that outermost electron.

the formation of CO2 from its elements in their standard states:

This reaction is exothermic, heat is released per mole of CO2 formed.

the reaction associated with the heat of formation of Sr S:

Heat is giving off, so the process is an exothermic process.

the reaction associated with the lattice energy of Na Br:

Lattice energy is exothermic. Lattice energy is the energy released when gaseous cations and anions associate with each other to form a solid.
