Use the following thermodynamic data to calculate ∆S° (universe) for the formation of HBr(g) from its elements at 298K in J/K. HINT: write the formation reaction for HBr(g)
Species ∆Hf° (kJ/mol) S° (J/Kmol) Species ∆Hf° (kJ/mol) S° (J/Kmol)
HBr(g) -36.3 198.59 Br2(g) 30.91 245.38
Br2(l) 0 152.23 H2(g) 0 130.6
