Br2 is being formed from HBr and H2O through the following chemical reactions under standard conditions: (1) HBr->1/2H2 +1/2Br2 and (2) H2O? H2 +1/2O2 The equilibrium constants at 1200 K for these reactions are given as K1 =2.24 × 10^?3 and K2 = 12.9 × 10^?9 . After reaching the equilibrium, the total pressure is 1 bar. a) What is the value for the equilibrium constant (K = KP ) at 1200 K for the reaction: 2HBr +1/2O2 ?? Br2 + H2O. b) What is the value of ?rG? at 1200 K temperature for the reaction in a)? c) Derive the equation for the partial pressure of Br2 in the equilibrium mixture for the reaction given in part a) at 1200 K when the reaction was initiated with the stoichiometric ratio of HBr and O2 (e.g., 2 moles of HBr and 1/2 mole of O2). Note: you are not required to solve the equation for [Br2].
