Use the following data to calculate the equilibrium constant K for the following reaction at 78?C: 2Br?(aq)+Cl2(g)?Br2(l)+2Cl?(aq) You
may assume that ?H? and ?S? are independent of temperature. ?H?f(Br?) = -121.5 kJ/mol ?H?f(Cl?) = -167.2 kJ/mol ?S?(Br?) = 82.4
J/(K?mol) ?S?(Cl?) = 56.5 J/(K?mol) ?S?(Br2) = 152.2 J/(K?mol) ?S?(Cl2) = 223.0 J/(K?mol)
