1. Molecular bromine is 24% dissociated at 1600 K and 1 bar (the total pressure is 1 bar) in the equilibrium Br2(g) 2Br(g). Calculate K at (i) 1600 K and (ii) 2000 K given that rH =+112 kJ/mol over the temperature range. Assume all gases behave ideally, and rH is constant over the studied temperature range. Assume at the initial state, the number of mole of Br2(g) and Br(g) is n mol and 0 mol, respectively.
