Question

For a reaction in which a diatomic molecule dis- sociates into atoms, what are the signs of ΔS and ΔH? Explain your answer. You may use the reaction N2(g) ⎯→ 2N(g) as an example of such a reaction.

Answer 1

For the reaction N2 (g) and 2N (g) the energy is required to break the bond in N2 to from N atoms. This means AH is positive, is an endothermic reaction.

Step-by-step explanation:

Entropy increases that is positive because atoms are now free to move.
