Forthe reaction,
2Cl(g)→ Cl2(g),what are the signs of ΔHand ΔS?
ΔHand ΔSarenegative
Thegiven reactionrepresents the formation of chlorine molecule from chlorine atoms.Here, bond formation is taking place. Therefore, energy is beingreleased. Hence, ΔHis negative.
Also,two moles of atoms have more randomness than one mole of a molecule.Since spontaneity is decreased, ΔSis negative for the given reaction.
