Question
9.) The equilibrium constant, Kp, for the reaction given below is 0.113 at 298 K, which
corresponds to a standard free-energy change of 5.4 kJ/mol. In a certain experiment, the initial
pressures are PN204 = 0.453 atm and PNO2 = 0.122 atm. Calculate AG for thereaction at these
pressures, and predict the direction in which the reaction will proceed spontaneously to establish
equilibrium. Show ALL work!
