Select the correct experimental facts.
For the reaction Hg (l) ———> Hg (g) , the entropy change will have the sign:
(i) Cis - 2 - butene → trans - 2 - butene, ΔH1
(ii) Cis - 2 - butene → 1 - butene, ΔH2
(iii) Trans - 2 - butene is more stable than cis - 2 - butene.
(iv) Enthalpy of combustion of 1 - butene, ΔH = -649.8 kcal/mol
(v) 9ΔH1 + 5 ΔH2 = 0
