At 25C, for the reaction Br2 (g) + 2Br (g) We have AG = 161.67 kJ/mol, and AH = 192.81 kJ/mol a. Compute the mole fraction of bromine atoms present at equilibrium at 25C and P = 1 atm b. At what temperature will the system contain 10 mol percent bromine atoms in equilibrium with bromine vapor at P = 1 atm.
