Hydrogen bromide, HBr, is a colourless gas. Consider itsdissociation reaction 2HBr (g) « H2 (g) + Br2 (g) DfHo (kJ/mol)-36.4 +30.9 So (J/K.mol) +198.7 +130.7 +245.5 ooo a) DetermineDeltaH , DeltaS , DeltaG , and Kp (all at T= 298 K) for thisreaction. b) A 100. mL constant volume reaction vessel is loadedwith 0.05 mol HBr and heated to 800 K. Calculate the equilibriumconstant for this temperature and the partial pressure of Br2 inthe equilibrium mixture. Assume Delta standard H and Delta standardS to be independent of temperature.
Correct Answers:
DHo=103.7 kJ/mol, DSo=-21.2 J/K mol, DGo=110.0 kJ/mol, K=5.25 x10-20
PBr2= PH2=3.78x x 10-3 atm (PHBr is essentially unchanged).
