For the reaction: Cl2(g) → 2Cl(g), _______.
(A) ΔH is positive, ΔS is positive
(B) ΔH is positive, ΔS is negative
(C) ΔH is negative, ΔS is negative
(D) ΔH is negative, ΔS is positive
उत्तर
(A) ΔH is positive, ΔS is positive
ΔH is positive as energy is required for bond breaking. ΔS is positive as the number of gaseous species increases.
