5.Fill in the electrons on the molecular orbital diagram below for oxygen,O2,and state why the molecule is or is not paramagnetic. 620 π20 T2p 620 62s 4 02s This molecule is paramagnetic because of the two unpaired electrons in theorbitals. Part B.Answer all four questions(20 marks each). 1(a)Use the data in the table below to calculate AG(kJ mo)for the reaction 25C △H°(kJmo 2.0 0 s°UKmo）2.0 6.0 △H°an=AH(Cseraphie)-AHCsdiamon时 =0-2 =-2 kJ mol AS=S(Csphite)-S(Cdiamond) =6.0-2.0 =+4 JK mol5. Fill in the electrons on the molecular orbital diagram below for oxygen, O2, and state why the molecule is or is not paramagnetic. π2p σ2p π∗ 2p σ* 2p σ* 2s σ2s This molecule is paramagnetic because of the two unpaired electrons in the π*2p orbitals. Part B. Answer all four questions (20 marks each). 1 (a) Use the data in the table below to calculate ΔGo (kJ mol-1) for the reaction C(s) diamond → C(s)graphite at 25o C: C(s) diamond C(s)graphite ΔHf o (kJ mol-1) 2.0 0 So (J K-1 mol-1) 2.0 6.0 ΔHo rxn = ΔHf o (C(s)graphite) - ΔHf o (C(s) diamond) =0 – 2 = -2 kJ mol-1 ΔSo rxn = Sf o (C(s)graphite) - Sf o (C(s) diamond) =6.0 – 2.0 = +4 J K-1 mol-1 2
