Question

For the reaction; 2Cl(g) ----> Cl2(g);
what will be the signs of ∆H and ∆S ?

Answer 1

$\huge{\textcolor{red}{\star{\mathcal{Answer :≈\star}}}}$

$\implies$∆H : Sign will be negative (- ve)

$\implies$because the energy is released in the formation of bond

$\implies$∆S : Sign will be negative (- ve)

$\implies$ because the entropy decreases when the atoms combines to form molecules.
